Vacuum Chamber Baking Update |
|
|
| The PID controllers were turned off on Friday and the chamber was left to cool over the weekend. Just took data and it looks like signal to noise ratio is pretty bad again. I do not know if this means we need a hotter bake or if the chamber needs some more time to cool down. I will overlay this data and make sure to take a second set a bit later to compare. Some good news though is that the chamber has reached a pressure below 10e-8 torr with the full range gauge above the RGA line reading 6.85 e-8 torr and still dropping. |
