BLM system for the PETS in 2004 • 6 Beam Loss Monitors are installed and distributed along the PETS Tank • The detectors are Aluminum Cathode Electron Multipliers. They have a fast time response (2ns) which allows to observe the time evolution of the beam losses. • All the BLM’s are supplied in parallel • Every signal can be amplified in the tunnel using a 26/46dB 300MHz amplifier card. • The output signals are then sent to fast Analog to Digital converters Rack 095 8 channels digitizer VME module 12 bits acquisition @ 96 MHz 0-2kV, 100mA Power supply Gallery Tunnel e- T.
