 Pulser set to 100 pps.

Shaping amp:
Gain: 1x1.0x50
Tau: 2 us
Negative polarity.


 

Entry  Thu Jul 28 16:00:43 2016, Sarah, List of to-dos 

Process alpha data
- Compare pulser width and alpha width to calibration spectra (shaping amp with 1us and gain 50x)
- Does photodiode data process OK or is it a problem with the oscillations?

Process LiF data
- Any pile up issues? Problems with gamma flash?

 

Online monitoring:
- Check leakage every few days, check lab temp.
- Check alpha peaks of 26Al contaminants - Gd, B.
