TI - Design, Development and Implementation of a Highly Dependable Magnet Powering Interlock System for ESS J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - 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.
