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 |

I have (fingers crossed) got the baking stepping up nicely now. I have used some of the outer shell to act as a shield and to direct airflow towards
the front and back of the baking volume. I also moved the RE-72 thermocouples to a higher temperature region and replaced the broken thermocouples. The
program is on automatic mode and has currently stepped up to 40C with the max diff reduced to ~4C. |

Fri Sep 4 15:48:25 2020, JM, Bakeout test completed
|
Bakeout test completed. Maximum temperature reached within baking volume was 120 degrees, with baking stopped by the program due to detection of
negative temperature gradients. Negative temperature gradients due to a couple of thermocouples becoming unsecured and moving to cooler part of baking
volume. Attached documents show temperatures of thermocouples. The colour of plots are linked (all of chamber temperatures are blue etc). Temperature |

Wed Sep 2 17:01:49 2020, JM, Bakeout started and valve installation
|
Initial bakeout started which will run until friday, temperature had reached 44 degrees when I left the lab.
The bottom valve has now been installed on the main chamber |

|
Attached are plots for the previous bakeout of CARME which may aid in the bakeout to come in the following week.
Plots relate the heater temperatures and heater powers with the chamber temperature (internal floating thermocouple) and pressure inside CARME. |

|
The Chamber has continued to pump overnight and we have reached a pressure of 3.3e-6 mbar as of 10:15. Power cable for the hot cathode gauge was found. Gauge
did not give a reading so pin connections were checked, all is okay so it may be thepressure is still too high within the chamber, gauge was thus turned
off. I have attached the RGA from this morning which has increased accuracy so has been cleared up for most of the noise from yesterday. I have begun |

Temperature in the baking volume is ~ 42 C and the pressure is 4.6e-8 mbar. Current heaters set point is 135 C. This will now be increased to
200 C to start increasing the baking temperature more significantly. |

Fri Feb 4 09:53:48 2022, JM, TD, OH (remotely), Alpha spectra overnight 8x
|
DAQ was left running last night from 19:30. Detector bias 80V with a leakage current ~3.4 uA. Pulser OFF.
Observed alphas in spectra overnightin the 20,000 to 28,000 channel range for the pn side and 36,000 to 44,000 range on the nn side of the detector.
Zero energy noise peak is at channel 32000. |
