Evaporator #2 Target Heater is now auto-ramping at 0.5 A/min, up to 820 A, with the maximum voltage limited at 2 V, between 2.00e-05 (Good vacuum) and 3.00e-05 Torr (Bad vacuum). Tube Heater is auto-ramping at 0.5 A/min, up to 230 A, with the maximum voltage limited at 1 V. See attachments.

Increased TBHT voltage to 5V, and TGHT to 15V.  Currently, TBHT =83A, 0.986V, TGHT= 144A, 1.65V, IGP1 = 5.2e-7 Torr, IGP2 = 4.3e-7 Torr. 

Continue ramping up...

TGHT and TBHT were ramped up to 830A/13.65V (local), and 235A/3.85V, respectively.  The target was conditioned over the long weekend.
