[Solid_ec] Scintillator pad detector for SBS GEP

[Jin Huang]

Dear All,

 

There is a design and test effort on going in Hall A, to build a detector
very similar to our photon rejecting scintillator pad. It consists of
scintillator pad, WLS fiber, and maPMT for readout:

 

Experiment: Hall A GEP in the SBS program

Spectrometer: BigCal

Purpose: provide electron trigger 

Sensitive layer: Scintillator pads with WLS fiber imbedded for readout

PMT: 16 channel maPMT retired from CDF. 

Electronics: (still in design) threshold detection with output for trigger
and TDCs. Each maPMT channel processed

Who to ask for more detail : Bogdan

 

What for SoLID:

* We may copy this design for photon-rejecting scintillator pad for the
SIDIS experiment

* There are few hundred 16 channel maPMT left in the pool, which we may
borrow or use!

* Proto-type test result that we may cite

* The amplitude/ADC info is not used and not implemented in their
electronics, but necessary if we use it for preshower

 

Cheers,

 

Jin
