Both the IEVAP2:TBHT and IEVAP2:TGHT maximum current setpoints on the vacuum page (see page: /edl/ievap2_vacuum1.edl) are wrong. 
For IEVAP2:TGHT, the maximum current setpoint should be 1500A (see page: /edl/ievap2tghtcp.edl), not 1000A.

Yesterday, a new target boat was sprayed with TaC coating and let dried.
The boat was then installed in the Evap#2 chamber and pumped down to 10-6 Torr before the target heater was turned on.  NOTE: Target boat
Entry  Tuesday, May 15, 2012, 12:26, John Wong, SiC, 38481-2, HP-SIS, Done, Re-condition the HP-SIS SiC target 
Tuesday, May 15, 2012, 12:24
The HP-SIS SiC target was made on Nov 03, 2010.  The target consists of 405 discs, 18.5cm in length.  It was sintered in the Evaporator#1. 
This target is going into Evap#2 for re-conditioning.  It is currently being pumped down.

 Tuesday, May 15, 2012, 13:45
It was discovered that one of the insulators that supported the target module broke apart (see Attachment#1).  This might be caused by the
heat from the target legs that reflected back from the base to the insulators.  The burnt marks are the evidence.

It was found that there were water droplets from the TBHT cooling line.  The joint is leaky.  (see attachment 1) 
A message has sent to Rick M.

The tube heater power supply current readback and setpoint are not matching.  Ray Dube checked the power supply and confirmed that it is faulty.
 He will replace a functional p/s tomorrow.
