8 days with Dust Monitor high on BSC2

Tuesday Aug 19th I moved the dust monitor #10 from the bier garten area to up on the work platform on BSC2 (alog86444). Attached are some various plots of DM10 and DM6, the monitor next to HAM6 in the mega clean room (turned off atm).

Attached a zoomed-in plot of the DM10 channels just around the maintenance period on Tuesday, Aug 26th while craning was happening overhead. Dust counts certainly spiked mid-morning, which is likely when craning was happening as seen by ITMY STS BLRMs.
