PePPO run
Currently scheduled Injector recovery on October 22
Positrons May be November 4 & 5
Currently max energy is 7.8 MeV.
Choosing 6.3 MeV incident electron energy because that is the most stable.

Region 3
The annihilation counter is labeled as IAC5D03 on the JLAb beam line
Cable length are 75-100 feet long
2 NaI detectors
Instead of using the mirrors described below, the NaI detectors were rotated in Phi to be out of the way of a camera view.
Old mirror design (not implemented)
one has mirror between it and the port window to reflect light to a camera.
See if we can send out one of our actuators to move the mirror in and out.
Aluminum WIndow pressure test
A 5 mil window bursts at 65 PSI
A 10 mil window bursts at 110 PSI
