Tuesday, July 16, 2019, 10:27: The idea of this run is to have the full 600 A from TGHT and the full 600 A from TBHT.

This will done based on the rewiring done previously (see entry 745)

Tuesday, July 16, 2019, 12:16: Jumper cable F-H burning while target was at 600 A total. Ramp up aborted and auto-cooling started to remove the jumper.

Jumper removed.

TBHT cables on both positive coil FT.

Jumper E-G removed.

High current cable connecting F-H.

Tuesday, July 16, 2019, 16:49

Current ramped up to 300A + 300A on TGHT and TBHT in parallel, for an equivalent of 600A on the target. No burn to anything noticed, PS ramping nicely together. Stopped ramping up and started ramp down for the night.

Using broken LP-FEBIAD oven. TBHT off.

Tuesday November 26, 2019 20:00: Thermocouple 3 gives signs to have a bad contact with the HS. "Luckily" it is the one attached to the HS itself. TH 1 and 2 show similar temperatures below 40degC at 500A. Ramping to 600A

 Tuesday November 26, 2019 20:46: 600A TH1 and 2 around 40degC slightly going down. Tomorrow it will be known the final steady-state temperature. The test shows tho that the temperature evolves similarly between the copper piece and the Peek assembly. Showing good contact.

Tried pumping down chamber with roughing pump. Looks like there is water in the system. Will leave it as is for now.

Tuesday, April 28, 2020, 12:30

Removed SiC#40 target and pumped down with HS lines blanked off. Used recycled SST gaskets.

Tuesday, April 28, 2020, 13:00

Still problem with water in the system. CG1 at about 25 Torr. Purging all water lines and pumping down again.
