GANIL High Intensity Transport Safety System

Abstract : IFor several years, GANIL has been allowed to reach a maximum beam power of six kilowatts (400W in normal mode) thanks to the THI system (High Intensity Transport System). Three modes of running are necessary to accelerate a THI beam ("Injector" mode, "tuning" mode and "surveillance" mode. The "surveillance" mode requires a safety system to protect equipments against beam losses. Inside cyclotrons, diagnostics measure beam losses current at the injection and extraction devices. Along beam lines, diaphragms measure beam losses current at the input and output of dipoles. Current transformers are used for the beam transmission measurements through beam lines and cyclotrons. The safety system controls beam losses and quickly reduces the beam intensity with a chopper if some losses overshoot thresholds. These thresholds can be monitored by software.
