Equipment Protection System for CBETA
- Brookhaven National Lab. (BNL), Upton, NY (United States)
The ultimate goal of CBETA is to be the first high-current multi turn Energy Recovery Linac operating at 40 mA. The power of highest energy beam at this configuration is going to be 6 MW. Hence equipment protection against radiation is an important issue. Through our stages of commissioning we will slowly increase the beam current, starting from 100 pA all the way to 1 mA during the current commissioning phase. The electron beams hitting any in-vacuum component either on purpose (e.g. view screens, beam stops or during commissioning) or due to some component failure will generate a radiation shower which has the potential to damage various parts of the accelerator. In this document, we describe the various scenarios which generate unwanted radiation in our machine and list the damage thresholds of critical components. Then we discuss our diagnostic systems which can detect component failure and the resulting radiation generated. We further list the possible beam modes of the machine which we have designed taking into account the damage thresholds and the sensitivity of the diagnostics. Finally, we document our design of the Equipment Protection System (EPS) and outline protocols of calibration and operation.
