sPHENIX discussion of electronics

[Nathan Grau <ngrau AT augie.edu>]

Hi Balazs,

Very nice and complete poster. I have only a couple of small comments on Section #6.

1) In the first sentence there are a few grammar things."Hamamatsu values operating voltage (Vop , the middle value for that tray) and gain (G) are given at 25 ◦C. In the tester, temperatures are measured by 25-25 (IV-SPS PCB) sensors. We measure the breakdown voltage (Vbr) and gain given in ADC units (Grel), the correlation is strong ±2% (except Tray 216)."

2) "Using the Hamamatsu 40mV for Vop " --> "Using the Hamamatsu V_op"

Thanks,

Nathan

Blazs-

The content looks good, however, it does not use the "sPHENIX"
template.  I did not check to make sure that the document meets QM-19
requirements.

Also, we have been saying that we expect neutron fluxes of order 10^11
per run, you have 10^10.

Please update the fluence number, the rest looks fine.  I will send you
directly the official template.  if it is a straight forward change, I
would prefer to use that to unify the sPHENIX posters.  If not, what you
have with the one update is fine.
