VME readout fro TOF

Particle 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 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 ms 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?
