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. 

Chamber has been pumped down and current vacuum at 1e-6 Torr. 

HS water check - good.

Target temperature 1400C

Ramping up to 250A; this should get to ~1300C.  Will let it heat for over night and step up to 1400C tomorrow.

I'm stopping the heating process because the camera is not working.  I can't monitor the temperature.  Tried to fit the camera; don't now why it fails to connect to the server. 

Will look in to it tomorrow...
