Full target loaded with ~500 non-active foils plus 4 active foils.  

Initial pressure when heating: 6.6E-5 T 

Manually went to:

TGHT=125 A 

TBHT=50 A

with increments of 5 A each. Pressure has little spikes but mostly unchanged (going down, actually).

Manually went to

TGHT=180 A 

TBHT=80 A

Pressure going up steadily, max pressure <2E-4

From TGHT=180 A, TBHT=80 A we are aiming at going to TGHT=580 A and TBHT=230 A in increments of 50 A each and leave it there for a total of 5 minutes after nominal parameters are reached. Initial pressure 1.3E-5 T.

Fast rampup done, we were up there in 30 seconds.

TGHT VOL = 6.6 V

TBHT VOL = 3 V

Max pressure 2E-3 T. Both TGHT and TBHT were shut off abruptly on purpose.
