A bunch of end caps (12?) and a long Ta-wire in spring sharp  were coated with TaC coating and wrapped in a small sheet of graphite foil. 

Container is then wrapped with a sheet of Ta heat shield.

These caps and wires will be sintered in Evap 1, so they may be prompted to contamination from the uranium processes. 

I have no choice but to use Evap1 to do this work since we are falling behind with the schedule.  

In the future, please have all the materials (targets, end caps, binder, etc) well prepared. 

I do not know what is the required current to sinter the caps since there is no temp measurement.  So, the best is to go with how the container was sintered, 580A.

Chamber has been pumped down to mid 10-6 Torr. 

Auto ramp to 580A at 2A/min.
