calibration : 0.491937+0.808439*evt.Chan For detector B
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("0.491937+0.808439*evt.Chan>>(4096,0,4096)","evt.ADCid==1");
Using the above calibration I see a line at 1766 leV with a half life of 2.56 min.

| The blue line represents the counts observed after 480 second, the red line are the counts observed during the next 480 second time interval | A fit to the counts observed over the first 480 seconds |
I see Cl-40 line at 2220 keV with half life of 1.35 min
There is a 630 keV line with a 219 second half life (= ln(0.5)/-0.003155)
Possible reactions
I see a line at 142 +/- 2 keV with a half life of about 474 seconds (7.9 min)
16:00: ran Se-Foil 50-50 by mass mixture was irradiate using the same conditions as above for
