	S.L. Birch, A. Nordt, D. Paulic ESS, Lund, Sweden
	Providing and assuring safe conditions for personnel is a key parameter required to operate the European Spallation Source (ESS). The ESS will be responsible for developing all of the facility personnel safety related systems. All of these systems will be developed by the Integrated Control Systems Division (ICS) and all will be designed, manufactured, commissioned and operated in accordance with the IEC61508 standard, with regard to functional safety for Electrical/Electronic and Programmable Electronic (E/E/PE) safety related systems. This paper describes the ESS Personnel safety system’s scope, strategy, initial design requirements, and methodology but also provides an update of the system design progress so far.

MOPTY050	Design, Development and Implementation of a Highly Dependable Magnet Powering Interlock System for ESS	power-supply, operation, software, hardware	1045
	M. Zaera-Sanz, S.L. Birch, A. Monera Martinez, A. Nordt ESS, Lund, Sweden
	Approximately 350 resistive magnets and 350 power supplies (PS) will be installed in the 600 m long linear accelerator (LINAC) at ESS, transporting the proton beam from the source to the target station. In order to protect this equipment from damage (e.g. due to overheating) and to take the appropriate actions required to minimise recovery time, a dedicated magnet powering interlock system is being designed. The magnet powering interlock system will safely switch off a PS upon the detection of an internal magnet or PS failure and inform the beam interlock system to inhibit further beam operation. The different failure modes and related mitigation techniques of magnets and their PS will be presented. Failures of the magnet cooling system can be detected for example by interlocking the opening of a thermo-switch or a flow-switch. To achieve the required level of dependability, an interlock system based on safety PLC technology, distributed safety PLC software programming tools, PROFINET fieldbus networking, and current loops for hardwired interlock signal exchanges, has been prototyped and will be discussed.

	For the FAIR (Facility for Antiproton and Ion Research) synchrotron SIS100 and the storage ring CR (Collector Ring), different RF cavity systems are currently being realized. In addition to the standard RF bucket generation and acceleration, these ring RF systems also allow more complex beam manipulations such as barrier bucket operation or bunch rotation in phase space. Depending on their purpose, the cavities are either loaded with ferrite material or with MA (Magnetic Alloy) ring cores. Independent of the type of cavity, a complete cavity system consists of the cavity itself, a tetrode-based power amplifier, a solid-state pre-amplifier, a supply unit including PLC (Programmable Logic Control), and an RF control system (so-called LLRF, low level RF system). In this contribution, the different systems are described, and their current status is presented.

WEPMN061	ESS PLC Controls Strategy	timing, controls, hardware, vacuum	3066
	D.P. Piso, P. Arnold, S.L. Birch, T. Gahl, T. Korhonen, A. Nordt, J.G. Weisend ESS, Lund, Sweden
	The European Spallation Source ESS AB is an accelerator-driven neutron spallation source. The Integrated Controls System (ICS) division is responsible for providing controls and monitoring for all parts of the machine (accelerator, target, neutron scattering systems and conventional facilities). Also, Accelerator Division, Target Division and other parts of the organisation will be deploying PLC Automation Systems. A large number of applications have been identified across all the facility where PLCs will be used: cryogenics, vacuum, water-cooling, fluid systems, power systems, and safety \& protection systems. This work describes the different activities put in place and proposes the strategy followed at ESS regarding PLC technologies. This strategy consists not only of the standardisation of a PLC vendor but also testing activities, generation of documentation and standardization of other aspects (for instance, regarding installation). The documentation about PLC controls integration and standardisation and the approach to insert PLCs in the different controls workflows are described. Finally, the results of different tests (PLC timing correlation) are shown.

WEPMN067	Upgrade of the TCDQ Diluters for the LHC Beam Dump System	vacuum, controls, survey, extraction	3079

	The TCDQ diluters are installed as part of the LHC beam dump system to protect the Q4 quadrupole and other downstream elements during a beam dump that is not synchronised with the abort gap, or in case of erratic firing of the extraction kickers. These diluter elements installed during Run 1 were compatible with beam up to 60 % of the nominal intensity, which was insufficient for the second run of the LHC. This paper describes the requirements for the upgrade done during the First Long Shutdown (LS1), to make the TCDQ compatible with the full 7 TeV LHC beam at intensities required for the future runs of the machine. Subsequently the mechanical design changes, implementation and commissioning of the TCDQ are reported.
