PSL environmental channels trends
DougC and RickS On Tuesday, we measured the minute trends of the environmental channels over the past week (see attached figure). Ch. 16 is (supposedly) the particle counter in the H1 Diode Room. Either the dust monitor is malfunctioning, or we are having a lot of dust events at the 100,000 count level.

Bugzilla ID 413 has been opened to address this apparent H1 Diode Room dust glitch issue. Attached are two plots, the first the trend of the particle counter (supposedly in the H1 Diode Room) over the past week and the second a detail of one of the glitches.

Did anyone enter the diode room and look at this dust monitor?
