I have attached two plots of the dust counts in the H1 PSL enclosure from 8 AM yesterday to 8 AM this morning, one from the laser room (Location 1) and the other from the anteroom (Location 2). These are from the newly installed Lighthouse Remote 3014 particle counters. The counts are normalized to particles per cubic foot. The samples run for 20 seconds with no hold time between them. The black traces are counts > .5 microns. The blue traces are counts > .3 microns (including > .5 microns). The scale for particle counts is on the left. The scale for temperature and relative humidity is on the right.
