Designing ESS Machine Protection Systems highly integrated into operations and commissioning


  • Enric BARGALLO

Primary authors


The machine protection (MP) systems are of the utmost importance to reach high availability and reliability in a particle accelerator driven facility such as ESS. Designing robust and reliable MP systems is essential to achieve low-risk operation, yet a smooth and highly available operation has to be facilitated. The ESS MP systems evolved throughout their iterative design processes in the effort of reaching robustness, reliability as well as flexibility. Even if the design process usually focusses on reaching high reliability (in the protective sense) as well as fast response time and other MP specific aspects, the overall perspective where smooth operation is allowed is sometimes not properly taken care of. However, to reach high availability and to interfere as little as possible into operations, these systems have to be thought in conjunction with the rest of the machine considering how it is meant to operate as a whole. This contribution will show how some of the ESS MP systems changed during their design phase in order to have an easier and more available operation yet maintaining a high degree of protection.
