	The European Spallation Source, ESS, is a source of spallation neutrons used for neutron scattering experiments, complementary to synchrotron light sources. ESS has very ambitious goals and experimentation with neutrons at ESS should be one or two orders of magnitude more performing compared to other sources. Each proton beam pulse generated by the linear accelerator will have a peak power of 125 MW. The machine’s equipment must be protected from damage due to beam losses, as such losses could lead to melting of e.g. the beam pipe within less than 5 microseconds. System-of-Systems engineering has been applied to deploy systematic and robust protection of the ESS machine. The ESS Machine Protection System of Systems (MP-SoS) consists of large-scale distributed systems, of which the components themselves are complex systems. Testing, verification and validation of the MP-SoS is rather challenging as each constituent system of the MP-SoS has its own management, functionality that is not necessarily designed for protection, and also the different system owners follow their own verification strategies. In this paper, we will present our experience gained through the first 3 beam commissioning phases, ESS has gone through so far. We will describe how we managed to declare MP-SoS to being ready for beam operation without complexifying the task, and we will present the challenges, issues, and lessons learned faced during the verification and validation campaigns.

TUMBCMO37	Personnel Safety Systems for ESS Beam on Dump and Beam on Target Operations	452

	The European Spallation Source (ESS) is a Pan-European project with 13 European nations as members, including the host nations Sweden and Denmark. ESS has been through staged installation and commissioning of the facility over the past few years. Along with the facility evolution, several Personnel Safety Systems, as key contributors to the overall personnel safety, have been developed and commissioned to support the safe operation of e.g. test stand for cryomodules Site Acceptance Test, test stand for Ion Source and Low Energy Beam Transport, and trial operation of the Normal Conducting Linac. As ESS is preparing for Beam on Dump (BoD) and Beam on Target (BoT) operations in coming years, PSS development is ongoing to enable safe commissioning and operation of the Linear Accelerator, Target Station, Bunker, and day-one Neutron Instruments. Personnel Safety Systems at ESS (ESS PSS) is an integrated system that is composed of several PSS systems across the facility. Following the experience gained from the earlier PSS built at ESS, modularized solutions have been adopted for ESS PSS that can adapt to the evolving needs of the facility from BoD and BoT operations to installing new Neutron Instruments during facility steady-state operation. This paper provides an overview of the ESS PSS, and its commissioning plan to support BoD and BoT operations.

TUPDP078	Management of Configuration for Protection Systems at ESS	695
	M. Carroll, G.L. Ljungquist, M. Mansouri, A. Nordt, D. Paulic ESS, Lund, Sweden
	The European Spallation Source (ESS) in Sweden is one of the largest science and technology infrastructure projects being built today. The facility design and construction include the most powerful linear proton accelerator ever built, a five-tonne, helium-cooled tungsten target wheel and 22 state-of-the-art neutron instruments. The Protection Systems Group (PSG) at ESS are responsible for the delivery and management of all the Personnel Safety Systems (PSS) and Machine Protection Systems (MPS), consisting of up to 30 PSS control systems and 6 machine protection systems. Due to the bespoke and evolving nature of the facility, managing the configuration of all these systems poses a significant challenge for the team. This paper will describe the methodology followed to ensure that the correct configuration is correctly implemented and maintained throughout the full engineering lifecycle for these systems.

TUPDP081	The ESS Fast Beam Interlock System - Design, Deployment and Commissioning of the Normal Conducting Linac	704
	S. Pavinato, M. Carroll, S. Gabourin, A.A. Gorzawski, A. Nordt ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility based in Lund, Sweden. Its linac will have an high peak current of 62.5 mA and long pulse length of 2.86 ms with a repetition rate of 14 Hz. The Fast Beam Interlock System (FBIS), as core system of the Beam Interlock System at ESS, is a critical system for ensuring the safe and reliable operation of the ESS machine. It is a modular and distributed system. FBIS will collect data from all relevant accelerator and target systems through ~300 direct inputs and decides whether beam operation can start or must stop. The FBIS operates at high data speed and requires low-latency decision-making capability to avoid introducing delays and to ensure the protection of the accelerator. This is achieved through two main hardware blocks equipped with FPGA based boards: a mTCA ’Decision Logic Node’ (DLN), executing the protection logic and realizing interfaces to Higher-Level Safety, Timing and EPICS Control Systems. The second block, a cPCI form-factor ’Signal Condition Unit’ (SCU), implements the interface between FBIS inputs/outputs and DLNs. In this paper we present the implementation of the FBIS control system, the integration of different hardware and software components and a summary on its performance during the latest beam commissioning phase to DTL4 Faraday Cup in 2023.
