We used the laser to align the degrader (see attached photos)
According to the LISE calculation, equivalent effective thickness for 6 mm of Carbon target is 4.5 mm thick Aluminum.
Therefore, we've set the degrader system as follow: |

|
As previously recorded (81), on Thur Oct 13th, A NIM crate failure caused preamp power loss to the HPGe's. While D4 recovered with nominally the
same resolution as before. G7 would not recieve power to the preamps without an alarm from the NIM crate.
It was determined that there was a short along the lines of +12V and Ground , -12V and Ground, and between +-12V. |
