10:00   Vessel P = 3.99e-8 mbar,  RGA P = 1.4e-6 mbar 

10:54   Vessel P = 3.89e-8 mbar,  RGA P = 1.4e-6 mbar

Vessel continues to pump down. Baking Jacket fully installed and testing of baking begins before leaving on automatic mode for the week. Some baking jacket pieces may need to be re-jigged a little for use in GSI with the interaction chamber but will be fine for this bakeout. Note that due to the valves 'being in the way' the front of the baking volume holds the majority of the heaters

During this testing phase I have noticed the vessel pressure increase slightly even with vessel temperatures of approx 30C. Pvessel = 5.66e-8 mbar currently. 

Automatic mode started 14:06. I will monitor to check everything is okay before letting it run over the weekend 

16:00 I have noticed that two of the thermocouples floating(back) and floating(top) may be damaged as they were giving sharp spikes in temperature. I have just removed these thermocouples so they should just read the picologger temp. The jacket looks like it is holding temperature quite well. I have set the temperature to 35C and am currently waiting for temperatures to equillibriate before putting back into automatic mode. Pvessel = 1.68e-7 mbar

19:00 Temperatures look good, I will begin bakeout tomorrow morning now, so if anything goes wrong its not in the middle of the night. Have a good weekend all!
