Cartridge #10 loaded with 213 plus 3 analysi discs

To be reduced inside a Ta container tube.  Tube wrapped in 3 Ta foil heatshields.

Reduction for 4 hours and then 8 hours @ 450A

Good Vacuum: 5.0e-04 Torr

Bad Vacuum: 5.0e-02 Torr

Initial pressure is 2.4 e-06 Torr

 Wednesday, October 11, 2023, 10:56

Starting heat ramp at 2A/min to 60A

First pressure bump observed at 60A

Allowing pressure to restabilize

Wednesday, October 11, 2023, 13:12

IGP1=2.6 e-5 Torr

continuing to heat at 2A/min

Wednesday, October 11, 2023, 13:35

another pressure bump observed around 90A (should go slowly in these current range).  Aborted ramp, waiting for pressure to stabilize.

pressure rose to around 2.5e-02 Torr (close to our bad pressure)

Wednesday, October 11, 2023, 13:52

IGP1=5.4e-04 Torr Start ramp at 2A/min

Wednesday, October 11, 2023, 17:53

Pressure has started to drop so increased ramp to 4A/min

 Wednesday, October 11, 2023, 18:18

 Second small pressure bump observed at 482A and 5.0 V.  Pressure falling.  Will leave at 500A for 4 hours . 

 Wednesday, October 11, 2023, 22:00

IGP1= 8.0 e-06 Torr

TGHT=500A, 5.2V

Initiate rampdown to 450A and will leave there for 8 hours

Thursday, October 12, 2023, 07:02

Initiate rampdown to zero.  IGP1=3.21e-06 Torr

TGHT= 450A, 4.6V
