Worked on evaluating the background after the installation of 8" thick Pb wall in accelerator room and installing a FC, Scintillator, and Phosphorous screen at the end of the 90 degree line.
12/13/12
Worked on establishing a small spot size on the Phosphorous target and then documenting the beam properties.
12/14/12
Worked on establishing a small spot size on the Phosphorous target and then documenting the beam properties.
12/19/12
When Target T1 goes in and Accelerator side lights up( as viewed by scintillator Kelly) and Illyusha (when next to the beam exit window) also lights.
There is no Pb around T1.
Lets directionally shield Illyusha (when positioned next to the hallway) to determine how much lead to add around T1.
