Cryo vacuum chamber |

CONTAMINATION: Black paint flecks throughout chamber |
|
|
I was setting up for some characterization measurements of the JPL PD and I noticed that there are flecks of black paint all through the chamber. There were a couple of visible bare sections on the wall of the inner shield where paint had been removed.

Monday I completed the vent that Aidan had started by turning off the cryocooler. During the afternoon I turned off the pumps, unbolted the chamber lid, and removed the radiation shield lids.
Next, Aidan was going to run some characterization measurements and determine whether to swap the diode or repeat with A1.
