PSL Enclosure Elevated Dust Counts
Peter K., Jeff B.   

   Today there have been elevated dust counts in the PSL laser room and in the Anti-Room. Trends over the past few weeks show several spikes of high counts in both rooms.

   The alarm level settings for the Anit-Room (DM 102) are set for clean 1000 (Minor alarm 700 counts, Major alarm 1000 counts). The PSL enclosure is set for Minor alarm at 140 counts and major alarms at 200 counts. 

   We are still looking into the cause of these spikes. 

P.S. Ops - Please let me know if you are getting dust monitor alarms and what the wind is doing at the time of the alarms.
