[Vetroc_daq_sbs] ADC gate-signal

[R. Evan McClellan]

ok, scripts are working now...

how do I load up the correct HV settings? and where is the instruction sheet?

Hey all,

I'm at ESB doing some checks. I just noticed the PMT high voltage is off(readback ~ 0 on all channels).
I closed and restarted the GUI, but it seems to be stuck at 0% on "Initialization in Progress"...

Should I power-cycle the raspberry-pi?

Carlos,

Any progress this morning? I'll come out to ESB between lunch and the TO training.

Hi all,

definitely, I don't understand what happen here. I don't find any coincidence between PMT signal and pulser. It is not due to the use of VETROC as level translator because I connected the pulser directly to the oscilloscope and nothing. 

I connected, with a T connector, the pocket pulser through a discriminator, then to the fan in/fan out module and the rest as normal trigger signal as before, and the other output from the pocket pulser to the NINO card and I got a beautiful coincidence (as expected). 

PMTs noisy? cross-talk? (I didn't see this effect in the fastbus test). 

I'll try tomorrow changing the pulser with very long period. I'll go to the Target Operator Training tomorrow afternoon. 

Any suggestions are welcome

Cheers

-Carlos
