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.

dE 0.05
PHDI 0.12


Check on PHDI pulser width:
205170 (first in beam run) - 1.1% FWHM (at 8275 ch)
205439 (01/09/16) - 1.0% FWHM (at 8008 ch)

Seems to be holding up OK at present.

  49   Thu Aug 10 10:05:48 2023 CLWGafchromics Foil

Gafchromics foil was mounted on empty brass frame back to back with Li sample

Neutron beam goes well through the sample. Centered ~1 cm from sample center. Conclusion: no changes needed (too risky to make it worse and it is ok now)
