SOlarPanel A Irradiation on Jack
Irradiated on Jack by placing samples just above the Radiator as shown in the picture.
Beam parameters: Irradiation Date : 5/23/18
Start Time: 09:07:30
Stop Time: 11:07:30
Rep Rate=300 Hz
I = 98 mA
Pulse Width = 10 usec
E = 38 MeV
The solar panel current output dropped 1 mA per hour during irradiation. The cove was too dark to produce a signal from ambient light. The observed signal was completely due to the electron beam.

Measurements started at 14:45:38, 2:38:08 (158 min, 9488 sec) after irradiation ended,
Add 9488 seconds to time below to get time since irradiation

| 0 | Cs-137 (661 keV line) #64121 55.5 cm away from face |
| 360 | Mn sample (1.7 g, 1.5 cm x 1.5 cm square, 847 keV) 55.5 cm away from face |

| 2560 | Solar Panel A 55.5 cm away from face (0.55% deadtime, 300 Hz DAQ rate) |
| 2880 | Cs-137 (661 keV line) #64121 55.5 cm away from face (1.1% deadtime, 350 Hz) |
| 3070 | Mn sample (847 keV) 55.5 cm away from face (13 % deadtime, 4600 Hz) |
| 3330 | Ignore (Mn source was too close) Cs-137 #129792 15 cm away from face(6 % deadtime, 2000 Hz) |
| 3600 | Cs-137 #129792 15 cm away from face(.5 % deadtime, 200 Hz) |
| 4000 | Solar Panel A 15 cm away from face (2 % deadtime, 880 Hz DAQ rate) |
