Friday, August 31, 2018, 12:27: Roughing.

Friday, August 31, 2018, 13:19: Turbo pumps started.

Wednesday, September 05, 2018, 11:03: RGA on.

***NOTE***

P (kW) = A*V

TGHT at 475/7.84V, temp at 1550 C (3.72 kW - Max operating target heating power)

Note:  To condition the nanoSiC, it is better to keep TBHT at 0A and ramp up TGHT to 475A while monitoring the vacuum.  Then step up TBHT; any increase in vacuum would indicate a local evaporation of nanoSiC close to the ionizer. 

Settings as per John Wongs instructions and found in https://elog.triumf.ca/TIS/Evaporator_2/414
