Thermocouple on CARME foot side (1-4) may have come loose judging from sudden jump in temperature at 14:30?

Mon Sep 27 17:53:35 2021, JM RSS , Baking Jacket upgrade + NEG controllers connected
|
Additional baking jacket sections for the turbo section arrived today. Baking was halted at ~11:00 to allow for the chamber to cool to install new sections.
New sections installed and baking restarted at 15:25. Jacket fits much better with gaps near the turbos and the motors now covered much better. Attached
are some photos. |

Baking automatically stopped due to negative gradient in on thermocouple for 10 minutes straight.
Not surprising giving we were baking at full power bu making little progress. We should have switched to manual
mode.

However note setpoint is at 102 C. It appears we are baking at full power, but too many heat losses?
Temperature gradient still increasing. May just be a matter of time.

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 |

CARME setup checked by vaccum group this morning.
Both IE514 gauges de-gassed. To de-gas on the CM52 controller select the channel and hold the right arrow for two seconds. The reading will flash
indicating the de-gassing procedure, this lasts for 2 minutes before completing. Flashing automatically stops once procedure finishes. Attached for convinience |

On 21/9/21 CARME was connected to the leak tester. Leak testing showed no apparent leaks, extra time required to reach <1e-4 mbar during initial turbo
pumpdown might be due to outgassing from additional installed components on the chamber. Turbo pump restarted

Ion pump, RGA and additional gauge installed on the chamber.
Our gauge is the one mounted above the NEG feedthrough, Michael's gauge is mounted below the feedthrough. Ion pump too large to install on
the top of the vessel, sufficient room on flange immediately next to this top flange. |

Laser surveying team worked till 11. Chamber was too high by 3mm close to the jet target and 6mm by the turbo pump (towards the dipole).
CARME lowered appropriate amount using bolts under CARME feet. Height checked using a laser on the centre point line of the middle flange turbo
end and mid point on the front of the chamber (see images). During lowering front foot swapped and valve supports moved slightly to give more clearance |
