calibration : -12.2744+/- 0.08 + 1.021+/- 0.0001*ADC[0]value 14:30: Ran 25B machine at 250 Hz, 90 mA, 4us Pulse Width, 21.5 MeV incident electrons for 1 hour, 870012 pulses.

Sample KQT-2 was placed right after Dans Pb-Ni sample.

File /data/IAC/Jade/Jade_4-18-17/JadeAccOff.txt is a 30 minute measurement 2 minutes after beam off

File /data/IAC/Jade/Jade_4-18-17/JadeAccOn.txt is a ~ 1 hour measurement after the accelerator was turned on and just after the above measurement ended.

I didn't see the Aluminum lines using

MPA->Draw("-12.2744+1.021*evt.Chan>>(4096,0,4096)","evt.ADCid=0");

I see Cl-40 line at 2220 keV with half life of 1.35 min

Therre is a 630 keV line with a 3 minute half life

16:00: ran Se-Foil 50-50 by mass mixture was irradiate using the same conditions as above for
