Mon May 9 16:09:35 2011: Target is wrapped with 3 Ta heatshields and the evaporator is begin pumped down.
Mon May 9 17:59:57 2011: Vac is @ 1.33e-5 Torr. TGHT was stepped up to 60A before starting the auto heating process (See Attachment#1: TGHT_ramping_up). Note: Although the vacuum is at low e-5 torr, this should be fine to start the TGHT because it takes a while to heat up the high power target.
Tue May 10 11:10:44 2011: TGHT reached to 820A and stayed for 4 hrs before ISAC Ops helped to begin the cooling process. (See Attachment#2: Overall process). |
