| Started Bake 8 today. Set the PID controllers to 120 C and will check in the morning for equilibrium temperatures for the lid and chamber wall. The chamber pressure was 2.13 e-8 torr before taking off the full range gauges.
After the bake is done on Saturday it will be cooled down and RGA data will be taken to measure the out gassing rate of the stainless steel fasteners inside the chamber. Then on Tuesday we will plan to vent and open the chamber again to put the macor inside and repeat the another low temp bake and then test the macor early in week 11. Then the next material will be the aluminum mounting hardware for mounting the heaters and that should hopefully be done before the end of week 11 so the heaters can be tested afterwards after being cleaned with vector alpha wipes. |
