[Solid_daq] [Solid_ec] Npe estimation from beam tests, suggestions on HV, and possible meeting on Monday?

[Xiaochao Zheng]

Hi again, as for the equation:

  (integrated FADC) = (8E-6)*Gain*Npe

where Gain is the PMT gain.

If anyone is curious, this estimate is very simple:

(integrated FADC) = (Npe)*(1.6E-19C)*(Gain)*(50ohm)*(4096/1V)/(4E-9 sec)

where (4096/V) is how the FADC reading corresponds to voltage, 50 ohm is the FADC input impedance, and 4E-9ns is the timing resolution of the FADC.

If anyone spots a mistake, please speak up!
