High power proton beam imaging and real-time machine protection
A real-time optical imaging system has been developed and commissioned at the European Spallation Source (ESS) to monitor the high-power proton beam at the tuning beam dump, and provide machine protection. The system employs chromium-doped alumina (Chromox) luminescent screens imaged by radiation-shielded optics and a CMOS camera. Real-time FPGA-based processing extracts beam size and position, de
