Final temperature for Type-B suspensions

In order to decide a final temperature at the BS-SR2 clean booth and SR3-SRM clean booth, I have identified the temperature at which the GAS filters of all the Type B suspensions were assembled.

Temperature; Date; klog BS SR2 SR3 SRM
BF GAS 26.5°C;  22.08.2017;  klog 3278 24.5-25°C;  13.02.2018; klog 4153 23.8-24°C;  06.04.2018; klog 4650 24°C;  12.04.2018;  klog 4688
SF GAS 26.5-27°C;  07.09.2017;  klog 3350 24.2°C;  07.03.2018;  klog 4365 23.8-24°C;  06.04.2018; klog 4650 24°C;  12.04.2018;  klog 4688
F0 GAS 27°C;  19.09.2017;  klog 3385 24.5-25°C;  11.09.2018;  klog 6080 22.5°C;  13.07.2018;  klog 5522 24.5-24.8°C;  28.11.2018;  klog 7175

Note1: For the SRM, I used the same data as for SR3.

Note2: The attached figure shows the temperature fluctuation for BS, SR2, SR3. And I have zoomed in this plot to get the exact temperature.

This means, that in average:

  • The BS GAS filters were assebled at 26.67°C.
  • The SR2 GAS filters were assebled at 24.57°C.
  • The SR3 GAS filters were assebled at 23.43°C.
  • The SRM GAS filters were assebled at 24.22°C.

I think that the best would be to set the BS-SR2 area at 25°C and the SR3-SRM area at 24°C, because in this way we wouldn't need to move the motors too much, and we wouldn't have to take the risk of getting one motor stuck at the upper or lower limit.
