| Abstract |
For the proton linear accelerators used in applications such as ADS, due to the nature of the operation, it is essential to have beam failures at the rate several orders of magnitude lower than usual performance of similar accelerators. In order to achieve this extremely high performance reliability requirement, in addition to hardware improvement, a failure tolerant design is mandatory. A compensation mechanism to cope with hardware failure, mainly RF failures of superconducting cavities, will be in place in order to maintain the high uptime, short recovery time and extremely low frequency of beam loss. The hardware implementation of the mechanism poses high challenges due to the extremely tight timing constraints, high logic complexity, and mostly important, high flexibility and short turnaround time due to varying operation contexts. We will explore the hardware implementation of the scheme using fast electronic devices and Field Programmable Gate Array (FPGA). In order to achieve the goals of short recovery time and flexibility in compensation algorithms, an advanced hardware design methodology including high-level synthesis will be used.
