= Cathode Voltage Effect on the Peak sensing Spectrum=
 +
 +
All the measurements have the same GEM voltage 2.87 kV, just cathode voltage changes.
 +
 +
[[File:peak_starting_3030v.png|400px ]]
 +
 +
the figure below shows the the spectrum when the cathode at 3.735 kV (865V higher than the top GEM's voltage), which reaches to the maxmum rate that DAQ can measure.
 +
 +
We have seen the distribution on the far right before.  Can't seem to find those old histograms though.  What happened to the work done in 2013
 +
 +
A: Do you mean the QDC measurements ? [[GEM performance QDC data graphs]]
 +
 +
Yes that is it, the voltages are very different now.

Why is the pedestal rate the same for shutter open and closed when Cathode voltage >3570
 +
 +
The data below are not complete for that day because of some difficulties, I will update them when I take the data today Sun. 12/07 (I am just copying the table).

Cathode Voltage Effect on the Peak sensing Spectrum

All the measurements have the same GEM voltage 2.87 kV, just cathode voltage changes.

Peak starting 3030v.png

the figure below shows the the spectrum when the cathode at 3.735 kV (865V higher than the top GEM's voltage), which reaches to the maxmum rate that DAQ can measure. 

We have seen the distribution on the far right before.  Can't seem to find those old histograms though.  What happened to the work done in 2013

A: Do you mean the QDC measurements ? GEM performance QDC data graphs

Yes that is it, the voltages are very different now.

Why is the pedestal rate the same for shutter open and closed when Cathode voltage >3570

The data below are not complete for that day because of some difficulties, I will update them when I take the data today Sun. 12/07 (I am just copying the table).

Peak sensing Measured Spectra 11/29/14

The bottle has been changed by Nov. 11, 2014.New measurements for the Psensing spectrum is considered, duration for each run is 5 min. unless is mentioned differently.

A signal starts to appear as the drift voltage is 40V.
