Tested the power supplies and locked up the HV cage.
Turned on the HV: 30kV.
Tomorrow we'll start up the heaters: 580A for the target and 280-300A for the tube. |

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)

HS target leg openings were milled. Short from previous test by the look of it. TBHT insulator on source side is cracked.
Wiring up top adjusted for better clearance. EE (K) Cap appears ok.

A new turbo has been installed. Eddie said the other one had crashed but not catastrophically. He recommends the test stand
be wiped clean before pumping because there is a fine layer of Aluminum dust on the chamber base.

The insulator for the tube heater was observed to be glowing with a blue shine when the target was on high voltage. The insulator was glowing
on the side closest to the 9-pin connector. See attached photo. |

I have removed the resistor/varistor combinations that go between the poles of the target and tube heaters, and between those two supplies. I tested
all the components to make sure they were still working after the sparks - for the record the varistors clamp at 23V, not 33V as implied by the schematic.
