Abstract :
The CEBAF beam can burn through the vacuum wall in approximately 100 μs. We have developed an inexpensive beam loss sensor that will unambiguously detect a true beam loss and shut off the beam within this time without tripping on moderate interference from other sources. We have incorporated a full system test into the system, with provision for direct replacement of faulty sensors without adjustment. We describe the sensors, the signal processing design, system test results, and characterization procedures
