|
I have rewired the test stand (service cap wiring only, not power supply wiring) to anode bias mode as shown in the diagram. This was not how it was
wired before, there are several things I have removed that appear to be newer additions. I also removed the burned cable between TBHT(-) and COIL(-), and
between the multipin feedthrough and ground (probably related to the other burned cable). |

On Tuesday the hard good vacuum level was changed from 7e-6 T to 1e-5 T to allow larger leak rates when testing FEBIAD.
Also this new level should allow faster heating rates (be mindful and cautious)
