Tagger Fixed Array & Pair Spectrometer Electronics Update
Hi Franz,
I have requested this information before but I have received no updates,
yet.
I am updating the information on the electronics system diagram for all
Hall D detectors. I would appreciate if you could provide some feedback.
Tagger Fixed Array:
1. Are passive splitters appropriate for the fixed spectrometer (PMTs)?
Passive (resistive) splitters will cut the amplitude of the signal in
half (TDC and ADC) but the S/N is maintained.
2. Are leading edge discriminators appropriate for the fixed spectrometer?
3. Is 60 ps resolution (LSB) sufficient?
4. Recently, the fADC250 requirements have been changed to 12-bit. Is
this appropriate?
Pair Spectrometer:
1. Is the PMT used the XP2020?
2. Is 60 ps resolution (LSB) sufficient?
Thanks for your attention.
Regards,
Fernando
