|
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). |

Thursday, January 21, 2021, 10:05: Anodeless Negative Bias On Surface Ion Source, or ANBOSIS (still working on the acronym). installed to

The SIS allow a more forgiving operation while calibrating such that other sources can have these type of measurements. |

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)

correlate with energy spread.

The system was vented to make clearance on the waterlines as a very small continuous discharge was observed.
The inspection revealed some marks on the HS water line (sideview photo). From the the bottom and from real close (zoom and backview photo) the
marks are quite noticeable with shinny copper in the middle and dark circles around. |
