The bakeout for our detector setup has started on the evening of 27.08.2019
We have a temperature sensor in the vacuum next to the detector.
The goal is to maximize bakeout temperature, while not going above 125°C at the detector/sensor.
Here is a daily protocol of temperatures and vacuum pressure
T_12 is the set value of the 1st and 2nd controller device
T_34 is the set value of the 3rd and 4th controller device
T_56 is the set value of the 5th and 6th controller device
T_sens is the temperature measured by the sensor close to the detector
