PePPO 2011Run
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.
= 0.5 mm on the Tungsten target (T1)

Region 3
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.
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
