Tantalum samples were loaded in a tantalum testing tube and installed in the EVAP2 to heat under vacuum for 3 days at 2000 degC (~500A, 4kW).
The temperature is measured with the Omega pyrometer (slope 0.98)

297 C discs were loaded onto a Ta tube wrapped in 3 Ta heatshields. (10 of which are analysis
discs).  They should be the first to be pushed out as they were loaded last.

It was found that after the last process, Evap#2 has broken insulators - the cylinder insulator that supports the target centre legs and the block
insulator that supports the terminals.

Heat treatment of 2 bullet-shaped Nb samples in a LP-SIS container; it is just that we don't have a target boat. 
Container is wrapped with 12" in total length.  A strip of Nb foil is used as an underlayer for the samples to sit on top.

The source of the poor vacuum in the backing line seems to be related to a dirty filter. We will try to find a replacement filter next week.
The problem seem to have started September 17th, when backing preassure CG1A went from 40 mTorr to 130 mTorr. CG1B remained around 30 mTorr.

Backing pump was making very loud high pitched noises during last couple processes in the evaporator.
Replaced with a new one this morning.
