Subject: Baking  

Baking halted on 23/9/21 16:16 as connection to TC08 module was lost. USB cable connection to TC08 module appears to have been damaged in shipment. USB hub and cable replaced, connection re-established and baking restarted 17:27. 

Ramping of baking limited to 40C by the maximum difference between parts of the chamber being too high, this safety feature prevents high thermal gradients. Limitation caused by uneven heating due to placement of heating elements resulting in the gate valve end of the chamber being much cooler than the rest of chamber. The pressure increased to ~8e-7mbar at 40C due to increased outgassing. Baking stopped at 07:00 24/9/21, heating elements were repositioned and the baking jacket reassembled. Code recompiled to include the rate and temperatures limits from elog 76.

Baking restarted at 10:00
