	We introduce a radiation-tolerant multi-application wireless IoT platform, specifically designed for deployment in harsh environments such as particle accelerators. The platform integrates radiation-tolerant hardware with the possibility of covering different applications and use cases, including temperature and humidity monitoring, as well as simple equipment control functions. The hardware is capable of withstanding high levels of radiation and communicates wirelessly using LoRa technology, which reduces infrastructure costs and enables quick and easy deployment of operational devices. To validate the platform’s suitability for different applications, we have deployed a radiation monitoring version in the CERN particle accelerator complex and begun testing multi-purpose application devices in radiation test facilities. Our radiation-tolerant IoT platform, in conjunction with the entire network and data management system, opens up possibilities for different applications in harsh environments.

	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The National Ignition Facility (NIF) is the world’s most energetic laser capable of delivering 2.05MJ of energy with peak powers up to 500 terawatts on targets a few mms in diameter. This enables extreme conditions in temperature and pressure allowing a wide variety of exploratory experiments from triggering fusion ignition to emulating temperatures at the center of stars or pressures at the center of giant planets. The capability enabled the groundbreaking results of December 5th, 2022 when scientific breakeven in fusion was demonstrated with a target gain of 1.5. A key aspect of supporting various experiments at NIF is the ability to custom shape the pulses of the 48 quads independently with high fidelity as needed by the experimentalists. For more than 15 years, the Master Oscillator Room’s (MOR) pulse shaping system has served NIF well. However, a pulse shaping system that would provide higher shot-to-shot stability, better power balance and accuracy across the 192 beams is required for future NIF experiments including ignition. The pulse shapes requested vary drastically at NIF which led to challenging requirements for the hardware, timing and closed loop shaping systems. In the past two years, a High-Fidelity Pulse Shaping System was designed, and a proof-of-concept system was shown to meet all requirements. This talk will discuss design challenges, solutions and how modernization of the pulse shaping hardware helped simple control algorithms meet the stringent requirements set by the experimentalists.

	Funding: This work was supported by the U.S. Department of Energy, Office of Science, Scientific User Facilities Division under Contract No. DE-AC05-00OR22725. Detector events at User Facilities require real-time fast transport of large data sets. Since construction, the SNS user facility successfully transported data using an in-house solution based on Channel Link LVDS point-to-point data protocol. Data transport solutions developed more recently have higher speed and more robustness; however, the significant hardware infrastructure investment limits migration to them. Compared to newer solutions the existing SNS LVDS data transport uses only parity error detection and LVDS frame error detection. The used channel link is DC coupled, and thus sensitive to noise from the electrical environment since it is difficult to maintain the same LVDS common reference potential over an extensive system of electronic boards in detector array networks. The SNS existing Channel Link* uses LVDS for data transport with clock of about 40 MHz and a mixture of parallel and serial data transport. The 7 bits per twisted pair in each clock cycle are transported over three pairs of Cat7 cable. The maximum data rate is about 840 Mbps per cat7 cable. The DS90CR217 or DS90CR218 and SN65LVDS32BD components are used with shielded Cat7 cabling in transporting LVDS data. Here we discuss noise mitigation methods to improve data transport within the existing as build infrastructure. We consider the role of shielding, ground loops, as well as specifically the use of toric ferrite insolation transformer for rf noise filtering. * K.

	The SBIR funded Helium Mass Flow Monitor System, developed by Jefferson Lab and Hyperboloid LLC, is designed to measure the health of cavities in a Cryomodule in real-time. It addresses the problem of cavities with low Q₀, which generate excess heat and evaporation from the 2 K super-fluid helium bath used to cool the cavities. The system utilizes a unique meter that is based on a superconducting component. This device enables high-resolution measurements of the power dissipated in the cryomodule while the accelerator is operating. It can also measure individual Cavity Q₀s when the beam is turned off. The Linux-based control system is an integral part of this device, providing the necessary control and data processing capabilities. The initial implementation of the Helium Mass Flow Monitor System at Jefferson Lab was done using LabView, a couple of current sources & a nano-voltmeter. Once the device was proven to work at 2K the controls transitioned to a hand wired PCB & Raspberry Pi interfaced to the open-source Experimental Physics and Industrial Control System (EPICS) control system. The EE support group preferred to support a LabJack T7 over the rPi. 12 chassis were built and the system is being deployed as the cryogenic U-Tubes become available.

WE3AO06	Deployment and Operation of the Remotely Operated Accelerator Monitor (ROAM) Robot	1077
	T.C. Thayer, N. Balakrishnan, M.A. Montironi, A. Ratti SLAC, Menlo Park, California, USA
	Funding: Work supported in part by the U.S. Department of Energy under contract number DE-AC02-76SF00515. Monitoring the harsh environment within an operating accelerator is a notoriously challenging problem. High radiation, lack of space, poor network connectivity, or extreme temperatures are just some of the challenges that often make ad-hoc, fixed sensor networks the only viable option. In an attempt to increase the flexibility of deploying different types of sensors on an as-needed basis, we have built upon the existing body of work in the field and developed a robotic platform to be used as a mobile sensor platform. The robot is constructed with the objective of minimizing costs and development time, strongly leveraging the use of Commercial-Off-The-Shelf (COTS) hardware and open-source software (ROS). Although designed to be remotely operated by a user, the robot control system incorporates sensors and algorithms for autonomous obstacle detection and avoidance. We have deployed the robot to a number of missions within the SLAC LCLS accelerator complex with the double objective of collecting data to assist accelerator operations and of gaining experience on how to improve the robustness and reliability of the platform. In this work we describe our deployment scenarios, challenges encountered, solutions implemented and future improvement plans.

WE3AO07	Measurement of Magnetic Field Using System-On-Chip Sensors	1083
	A. Sukhanov BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Magnetic sensors have been developed utilizing various physical phenomena such as Electromagnetic Induction, Hall Effect, Tunnel Magnetoresistance(TMR), Giant Magnetoresistance (GMR), Anisotropic Magnetoresistance (AMR) and Giant Magnetoimpedance (GMI). The compatibility of solid-state magnetic sensors with complementary metal-oxide-semiconductor (CMOS) fabrication processes makes it feasible to achieve integration of sensor with sensing and computing circuitry at the same time, resulting in systems on chip. In this paper we describe application of AMR, TMR and Hall effect integrated sensors for precise measurement of 3D static magnetic field in wide range of magnitudes from 10^-6 T to 0.3 T, as well as pulsed magnetic field up to 0.3 T.

THPDP021	Equipment Life-Cycle Management at EuXFEL	1346
	N. Coppola, B.J. Fernandes, P. Gessler, S. Hauf, S.T. Huynh, N. Jardón Bueno, M. Manetti EuXFEL, Schenefeld, Germany
	Scientific instruments at the European X-Ray Free Electron Laser Facility (EuXFEL) comprises of a large variety of equipment, ranging from controllers, motors and encoders to valves. It is a false assumption that once a specific equipment had been procured and integrated, that no further attention is required. Reality is much more complex and incorporates various stages across the entire equipment life-cycle. This starts from the initial selection, standardization of the equipment, procurement, integration, tracking, spare part management, maintenance, documentation of interventions and repair, replacement and lastly, decommissioning. All aspects of such a life-cycle management are crucial in order to ensure safe and reliable operation across the life time of the equipment, whether it be five years, twenty years, or longer. At EuXFEL, many aspects of the described life-cycle management are already carried out with dedicated tools. However some aspects rely on manual work, which requires significant effort and discipline. This contribution aims to provide an overview of the requirements, and the ongoing efforts to develop and establish a complete life-cycle management at the EuXFEL.

	Funding: Swiss National Science Foundation, Switzerland; Ministry of Education, Science and Technological Development, Serbia. The Electromagnetic Calorimeter (ECAL) is a subdetector of the CMS experiment. Composed of a barrel and two endcaps, ECAL uses lead tungstate scintillating crystals to measure the energy of electrons and photons produced in high-energy collisions at the Large Hadron Collider (LHC). The LHC will undergo a major upgrade during the 2026-2029 period to build the High-Luminosity LHC (HL-LHC). The HL-LHC will allow for physics measurements with one order of magnitude larger luminosity during its Phase-2 operation. The higher luminosity implies a dramatic change of the environmental conditions for the detectors, which will also undergo a significant upgrade. The endcaps will be decommissioned and replaced with a new detector. The barrel will be upgraded with new front-end electronics. A Sniffer system will be installed to analyse the airflow from within the detector. New high voltage and water-cooled, radiation tolerant low voltage power supplies are under development. The ECAL barrel safety system will replace the existing one and the precision temperature monitoring system will be redesigned. From the controls point of view, the final barrel calorimeter will practically be a new detector. The large modification of the underlying hardware and software components will have a considerable impact in the architecture of the detector control system (DCS). In this document the upgrade plans and the preliminary design of the ECAL DCS to ensure reliable and efficient operation during the Phase-2 period are summarized.

THPDP078	Porting OpenMMC to STM32 Microcontrollers for Flexible AMC Development	1529
	M.B. Stubbings, E.P.J. Perez Juarez, L.T. Stant DLS, Oxfordshire, United Kingdom A. Wujek CERN, Meyrin, Switzerland
	Diamond Light Source has chosen the MicroTCA platform for high performance data acquisition and controls as part of the Diamond-II 4th generation light source upgrade. One requirement is the ability to create custom advanced mezzanine cards (AMCs) for signal conditioning and interlock support. To facilitate this, a module management controller (MMC) is required to negotiate payload power and communications between the AMC and MicroTCA shelf. A popular open-source firmware for controlling such a device is OpenMMC, a project from the Brazillian Light Source (LNLS), which employs a modular approach using FreeRTOS on ARM microcontrollers. Initially, OpenMMC supported the NXP LPC series of devices. However, to make use of Diamond’s existing ST Microelectronics (STM32) infrastructure, we have integrated a CERN fork of the project supporting STM32 microcontrollers into OpenMMC. In this paper, we outline our workflow and experiences introducing a new ARM device into the project.

THPDP086	LCLS-II Cryomodule Isolation Vacuum Pump System	1551
	S.C. Alverson, D.K. Gill, S. Saraf SLAC, Menlo Park, California, USA
	Funding: Work supported by the U.S. Department of Energy under contract number DE-AC02-76SF00515 The LCLS-II Project at SLAC National Accelerator is a major upgrade to the lab’s Free Electron Laser (FEL) facility adding a new injector and superconducting linac. In order to support this new linac, a vacuum pumping scheme was needed to isolate the liquid helium lines cooling the RF cavities inside the cryomodules from outside ambient heat as well as to exhaust any leaking helium gas. Carts were built with support for both roughing and high vacuum pumps and read back diagnostics. Additionally, a Programmable Logic Controller (PLC) was then configured to automate the pump down sequence and provide interlocks in the case of a vacuum burst. The design was made modular such that it can be manually relocated easily to other sections of the linac if needed depending on vacuum conditions. * https://lcls.slac.stanford.edu/lcls-ii

THSDSC02	A High Resolution Multichannel Acquisition System for Magnetic Measurements of Fusion Experiments
	R. Cavazzana, M. Brombin, G. Manduchi, A. Rigoni, L. Trevisan Consorzio RFX, Padova, Italy F.M. Milan ELAD, Sarone di Caneva (PN), Italy
	Magnetic fusion experiments rely mainly on coil loops as the primary type of magnetic sensors, offering precision, reliability, and robustness. However, to analyze the magnetic field, the sensors signals need to be time-integrated. Usually, analog integrators were employed due to their wide dynamic range, but they present complexity challenges. The need for a separate channel for the derivative (dB/dt) signals is also required to measure fast events, plasma instabilities, and magnetic turbulences. In this work, we propose a novel system design based on high-resolution analog-to-digital converters (ADCs) that eliminates the need for analog integrators and the second acquisition channel, simplifying the overall system. The system uses 1 MS/s, 20-bit ADCs, electrically comparable to good analog integrators. To ensure accurate measurements, each acquisition channel is electrically isolated, effectively eliminating the ground loops generated by the experiment’s magnetic fields. The system architecture is implemented on 6U boards, where each board serves as an autonomous system housing 12 input channels and its own SOC-FPGA, with a total of 144 channels on a 6U sub-rack. Each board simultaneously provides three essential functionalities: a timing synchronization decoder, transient recording of full-speed ADC data, and continuous Ethernet UDP transmission of subsampled signals to the real-time control system. This comprehensive approach allows for efficient data acquisition, analysis, and integration into the experiment’s control framework.

Although designed to be remotely operated by a user, the robot control system incorporates sensors and algorithms for autonomous obstacle detection and avoidance. We have deployed the robot to a number of missions within the SLAC LCLS accelerator complex with the double objective of collecting data to assist accelerator operations and of gaining experience on how to improve the robustness and reliability of the platform. In this work we describe our deployment scenarios, challenges encountered, solutions implemented and future improvement plans.

Magnetic sensors have been developed utilizing various physical phenomena such as Electromagnetic Induction, Hall Effect, Tunnel Magnetoresistance(TMR), Giant Magnetoresistance (GMR), Anisotropic Magnetoresistance (AMR) and Giant Magnetoimpedance (GMI). The compatibility of solid-state magnetic sensors with complementary metal-oxide-semiconductor (CMOS) fabrication processes makes it feasible to achieve integration of sensor with sensing and computing circuitry at the same time, resulting in systems on chip. In this paper we describe application of AMR, TMR and Hall effect integrated sensors for precise measurement of 3D static magnetic field in wide range of magnitudes from 10^-6 T to 0.3 T, as well as pulsed magnetic field up to 0.3 T.

Scientific instruments at the European X-Ray Free Electron Laser Facility (EuXFEL) comprises of a large variety of equipment, ranging from controllers, motors and encoders to valves. It is a false assumption that once a specific equipment had been procured and integrated, that no further attention is required. Reality is much more complex and incorporates various stages across the entire equipment life-cycle. This starts from the initial selection, standardization of the equipment, procurement, integration, tracking, spare part management, maintenance, documentation of interventions and repair, replacement and lastly, decommissioning. All aspects of such a life-cycle management are crucial in order to ensure safe and reliable operation across the life time of the equipment, whether it be five years, twenty years, or longer. At EuXFEL, many aspects of the described life-cycle management are already carried out with dedicated tools. However some aspects rely on manual work, which requires significant effort and discipline. This contribution aims to provide an overview of the requirements, and the ongoing efforts to develop and establish a complete life-cycle management at the EuXFEL.

The Electromagnetic Calorimeter (ECAL) is a subdetector of the CMS experiment. Composed of a barrel and two endcaps, ECAL uses lead tungstate scintillating crystals to measure the energy of electrons and photons produced in high-energy collisions at the Large Hadron Collider (LHC). The LHC will undergo a major upgrade during the 2026-2029 period to build the High-Luminosity LHC (HL-LHC). The HL-LHC will allow for physics measurements with one order of magnitude larger luminosity during its Phase-2 operation. The higher luminosity implies a dramatic change of the environmental conditions for the detectors, which will also undergo a significant upgrade. The endcaps will be decommissioned and replaced with a new detector. The barrel will be upgraded with new front-end electronics. A Sniffer system will be installed to analyse the airflow from within the detector. New high voltage and water-cooled, radiation tolerant low voltage power supplies are under development. The ECAL barrel safety system will replace the existing one and the precision temperature monitoring system will be redesigned. From the controls point of view, the final barrel calorimeter will practically be a new detector. The large modification of the underlying hardware and software components will have a considerable impact in the architecture of the detector control system (DCS). In this document the upgrade plans and the preliminary design of the ECAL DCS to ensure reliable and efficient operation during the Phase-2 period are summarized.

Diamond Light Source has chosen the MicroTCA platform for high performance data acquisition and controls as part of the Diamond-II 4th generation light source upgrade. One requirement is the ability to create custom advanced mezzanine cards (AMCs) for signal conditioning and interlock support. To facilitate this, a module management controller (MMC) is required to negotiate payload power and communications between the AMC and MicroTCA shelf. A popular open-source firmware for controlling such a device is OpenMMC, a project from the Brazillian Light Source (LNLS), which employs a modular approach using FreeRTOS on ARM microcontrollers. Initially, OpenMMC supported the NXP LPC series of devices. However, to make use of Diamond’s existing ST Microelectronics (STM32) infrastructure, we have integrated a CERN fork of the project supporting STM32 microcontrollers into OpenMMC. In this paper, we outline our workflow and experiences introducing a new ARM device into the project.

The LCLS-II Project at SLAC National Accelerator is a major upgrade to the lab’s Free Electron Laser (FEL) facility adding a new injector and superconducting linac. In order to support this new linac, a vacuum pumping scheme was needed to isolate the liquid helium lines cooling the RF cavities inside the cryomodules from outside ambient heat as well as to exhaust any leaking helium gas. Carts were built with support for both roughing and high vacuum pumps and read back diagnostics. Additionally, a Programmable Logic Controller (PLC) was then configured to automate the pump down sequence and provide interlocks in the case of a vacuum burst. The design was made modular such that it can be manually relocated easily to other sections of the linac if needed depending on vacuum conditions.

Magnetic fusion experiments rely mainly on coil loops as the primary type of magnetic sensors, offering precision, reliability, and robustness. However, to analyze the magnetic field, the sensors signals need to be time-integrated. Usually, analog integrators were employed due to their wide dynamic range, but they present complexity challenges. The need for a separate channel for the derivative (dB/dt) signals is also required to measure fast events, plasma instabilities, and magnetic turbulences. In this work, we propose a novel system design based on high-resolution analog-to-digital converters (ADCs) that eliminates the need for analog integrators and the second acquisition channel, simplifying the overall system. The system uses 1 MS/s, 20-bit ADCs, electrically comparable to good analog integrators. To ensure accurate measurements, each acquisition channel is electrically isolated, effectively eliminating the ground loops generated by the experiment’s magnetic fields. The system architecture is implemented on 6U boards, where each board serves as an autonomous system housing 12 input channels and its own SOC-FPGA, with a total of 144 channels on a 6U sub-rack. Each board simultaneously provides three essential functionalities: a timing synchronization decoder, transient recording of full-speed ADC data, and continuous Ethernet UDP transmission of subsampled signals to the real-time control system. This comprehensive approach allows for efficient data acquisition, analysis, and integration into the experiment’s control framework.
