Thermocouple Feedthrough is Ready

an, I have been waiting long enough for testing my awesome coldfinger in action. Now I'm close to there like never before. The thermocouple feedthrough is ready. Since I will be using two different types of thermocouples, I have downloaded NIST thermocouple tables and made a file to convert voltage readings to temperatures. I have finished calibrating the table using ice. Once I do another run with a liquid nitrogen, everything will be good to go.

One bad news is that we have run out of the copper junctions (shown in the picture). I have to get one on Monday and that will delay the real test run by about five or six days. (sigh...)
