A P2N target was carbothermal reduced but at the maximum current, the power supply tripped (elog. 267)

Therefore, the target was not hot long enough to fully outgas, that is why it will be reheated.

Desired current 650 A


Thursday, September 10, 2020, 14:07 

IGP1 =  3.3e-6 Torr

Autoramp set to 650 A at 1 A/10 s

Ramp reached desired current

TGHT = 2.4 V, 649 A

IGP1 = 3e-3 Torr 


 Friday, September 11, 2020, 11:17

TGHT = 2.24 V, 649.2 A

IGP1 = 3.7e-6 Torr


Friday, September 11, 2020, 12:55 

 TGHT = 2.2 V, 648.8 A

IGP1 = 3.7e-6 Torr

Autoramp set to 700 A at 1 A/10 s,

No more gas was released, the system was ramped down to 0 A at 2 A/min


Friday, September 11, 2020, 18:17

TGHT = 0.35 V, 133 A

IGP1 = 2.7e-6 Torr


 Friday, September 11, 2020, 20:01

TGHT = 0 V, 2.56 A

IGP1 = 2.6e-6 Torr
