Optics Lab Cleanroom On/Off Test

We've been running with both the cleanrooms in the Optics Lab and the flowbench furthest from the door running. Robert said that in the past (23169 ?) we haven't seen noise from these but should repeat the test now we have higher sensitivity.

Cleanrooms and flow-bench turned off for 8 minute intervals at below times (-/+5 seconds).

I investigated these times as part of my DetChar DQ shift. I see no evidence for any difference in the noise distribution during the tests.
