Each endcap is wrapped separately with a sheet of graphite foil and stacked in the target boat [see image] The target boat is wrapped with 3-layers of Ta-heat shield. The boat is installed in EVAP2, chamber is currently being pumped down.  Wednesday, May 27, 2015, 08:50 HS water valves opened, no leaks detected. Stepped up manually to 35A. Initiated auto-ramp at 0.2A/min yesterday afternoon. TGHT = 254A, 3.56V. IGP1 = 5.9e-7 Torr. Increasing ramping rate to 1.0A/min with a max setpoint of 400A.    Wednesday, May 27, 2015, 17:51 TGHT has been at 400A for almost 6 hours.  Temp at 1500C. Cooling down to 0A at 1A/min.
