Particle ID in beamlineParticle ID in beamline Our motivation: we are building a PID hodoscope for the MICE

beamline

PMTs XP2020 or EMI 9954 Segmented BC-404

The readout for the PMTs needs to be performed using TDC and ADCs on a VME crate to improve DAQ speed.

We also need DAQ at RAL to perform beam tests to validate the MICE beamline

VME modules neededVME modules needed We propose to use VME based TDC and ADC for the TOF of the

tracker test beam at KEK that can also be used later on for the PID hodoscopes at RAL.

Need to acquire:– Charge integrating ADC for VME. For example LeCroy 1182 (8

channels per module, 50 fC/count, 12 bits, 16 event buffer, fast clear 650 ns, 5 Megawords/s, 16 s conversion time) but other models available (e.g. CAEN)

– TDC for VME: need to define model We already have a (half) VME crate We could benefit from the test beam DAQ (unidaq) for future RAL

beamline PID test Question: what model ADC and TDC do you currently use?
