2020-08-05 7.13pm Roughing pump on

2020-08-06 10:48am Turbo was turned on by Marla in the morning. Vacuum IGP1 4e-6Torr. Water leak check performed, everything good to start heating up target. Waiting for Anders confirmation to start.

2020-08-06 4:38pm after changing setup to metallic connections only. Roughing on. After some minutes abnormal behavior in vacuum.

Turning water off to see if it is a small water leak.

Water purged, no change in vacuum.

IEVAP2:RV1 was closed. After opening, normal vacuum behavior recovered. The valve is automatically closing when reaching 100Torr. Wasn't doing that before. Turbo on now.

2020-08-07 9:24am pumping over night, vacuum at 8e-7torr. Everything ready for test. Ramping up target heater.Up to 50A 1A/20s

2020-08-07 9:48am all good at 50A, ramping to 250 1A/10s

2020-08-07 10:27am all good at 250A, ramping to 400 1A/10s

2020-08-07 10:57am all good at 400A, ramping to 500 1A/10s

2020-08-07 11:17am Tc type C might have been deatached at 500A, ramping to 600 1A/10s

2020-08-07 11:37am All good, ramping to 700 1A/10s

2020-08-07 11:58am 1950degC on pyrometer, 1200degC on type C TC (probably not well attached anymore), TCs on heatshield [30-40]degC. Pressure 9e-6Torr

2020-08-07 12:44pm All values stable after 45min, starting to ramp up parasitic target heating elements.

2020-08-07 1:15pm Open circuit, would seem that one of the heating elements cracked. Cooling down the target.
