5948	100, 7	1.15	shutter open, detector is on, no signal overlapping, reached to te signal highest rate, with almost 100% signal to noise ratio.

The following run has the same setting as the last run, unless there is achange written in the notes.

Charge Calibration

The peak sensing ADC was calibrated using stanford pulse generator, using hte same settings for the spectroscopic amplifier (coarse gain is 100, intergrate is 1, BLR high), the amp. (bipolar) output is delayed then send to the peak sensing ADC ch#7.
