Tunnel Gallery Girders x ADC’s HV Power supply Rack channels digitizer VME module (SIS3300), 12 bits 96 MHz with up to 256 ksamples extendable to 1024 ksamples HV channels (0-2kV, 3mA) 10 BLM systems to be installed in the CTF3 linac : 1 per section (or girder) Each system is composed by 4 detectors. All the detectors is supplied in parallel by the same high voltage unit. Each system has its own amplifier card and provides 4 signals to the ADC’s e-e- Injector T.
