TUMBCMO04	Real-Time Visualization and Peak Fitting of Time-of-Flight Neutron Diffraction at VULCAN	neutron, detector, EPICS, experiment	346
	B.A. Sobhani, Y. Chen ORNL, Oak Ridge, Tennessee, USA
	In neutron scattering experiments at the VULCAN beamline at SNS, Gaussian fitting of dspace peaks can be used to summarize certain material properties of a sample. If this can be done in real time, it can also assist scientists in mid-experiment decision making. This paper describes a system developed in EPICS for visualizing dspace evolution and fitting dspace peaks in real-time at the VULCAN beamline.

TUMBCMO07	Dynamic Control Room Interfaces for Complex Particle Accelerator Systems	interface, controls, operation, embedded	351
	B.E. Bolling, G. Fedel, M. Muñoz, D.N. Nordt ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Commissioning of the first part of the accelerator has begun and the requirements on the control system interfaces varies greatly as progress is made and new systems are added. In this paper, three such applications are discussed in separate sections. A Navigator interface was developed for the control room interfaces aimed towards giving operators and users a clear and structured way towards quickly finding the needed interface(s) they need. The construction of this interface is made automatically via a Python-based application and is built on applications in any directory structure both with and without developer interference (fully and semi-automatic methods). The second interface discussed in this paper is the Operations Accelerator Synoptic interface, which uses a set of input lattices and system interface templates to construct configurable synoptic view of the systems in various sections and a controller panel for any selected system. Lastly for this paper there is a configurable Radio Frequency Orchestration interface for Operations, which allows in-situ modification of the interface depending on which systems and components are selected.

	A touch screen (mobile or not mobile) has a significant impact on the kind of interaction between humans and control systems. This paper describes the development of some widgets and applications based on touch screens. The technologies used (for example PUMA, JavaScript and SVG) will be discussed in detail. Also a few tests and use-cases will be described compared with normal screens, mouse and keyboard interaction.

TUPDP132	Temperature Control of Crystal Optics for Ultrahigh-Resolution Applications	controls, EPICS, optics, power-supply	899
	K.J. Gofron ORNL, Oak Ridge, Tennessee, USA Y.Q. Cai, D.S. Coburn, A. Suvorov BNL, Upton, New York, USA
	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 The temperature control of crystal optics is critical for ultrahigh resolution applications such as those used in meV-resolved Inelastic Scattering. Due to the low count rate and long acquisition time of these experiments, for 1-meV energy resolution, the absolute temperature stability of the crystal optics must be maintained below 4 mK to ensure the required stability of lattice constant, thereby ensuring the energy stability of the optics. Furthermore, the temperature control with sub-mK precision enables setting the absolute temperature of individual crystal, making it possible to align the reflection energy of each crystal’s rocking curve in sub-meV resolution thereby maximizing the combined efficiency of the crystal optics. In this contribution, we report the details of an EPICS control system using PT1000 sensors, Keithley 3706A 7.5 digits sensor scanner, and Wiener MPOD LV power supply for the analyzer crystals of the Inelastic X-ray Scattering (IXS) beamline 10-ID at NSLS-II**. We were able to achieve absolute temperature stability below 1 mK and sub-meV energy alignment for several asymmetrically cut analyzer crystals. The EPICS ePID record was used for the control of the power supplies based on the PT1000 sensor input that was read with 7.5 digits accuracy from the Keithley 3706A scanner. The system enhances the performance of the meV-resolved IXS spectrometer with currently a 1.4 meV total energy resolution and unprecedented spectral sharpness for studies of atomic dynamics in a broad range of materials.

THSDSC06	Developing a Digital Twin for BESSY II Synchrotron Light Source Based on EPICS and Microservice Design	synchrotron, EPICS, controls, monitoring	1594
	W. Sulaiman Khail, M. Ries, P. Schnitzer HZB, Berlin, Germany
	Digital twins, i.e. theory and design tools connected to the real devices and machine by mapping of physics components to the technical correspondents, are powerful tools providing accelerators with commissioning predictions and feedback capabilities. This paper describes a new tool allowing for greater flexibility in configuring the modelling part combined with ease of adding new features. To enable the various components developed in EPICS, Python, C, and C++ to work together seamlessly, we adopt a microservice architecture, with REST API services providing the interfaces between the components. End user scripts are implemented as REST API services, allowing for better data analysis and visualization. Finally, the paper describes the integration of dash and ploty for enhanced data comparison and visualization. Overall, this workflow provides a powerful and flexible solution for managing and optimizing BESSY II digital twins, with the potential for further customization and extension to upcoming machines.

FR2AO05	Python Library for Simulated Commissioning of Storage-Ring Accelerators	MMI, simulation, storage-ring, closed-orbit	1637

	Simulations of the commissioning procedure became vital to the storage-ring lattice design process. The achievable tolerances on lattice imperfections, such as equipment misalignments or magnet gradient errors, would, without correction, prohibit reaching the design parameters. We present a Python library which includes an extensive set of error sources in the accelerator lattice and provides a variety of correction algorithms to commission a storage ring. The underlying beam dynamics simulations are performed with pyAT. This project builds upon previous works and expands them in the direction of realistic control room experience and software maintainability. The performance is demonstrated using example commissioning studies, and further development plans are discussed.
