All equipment status updates.


There was a report of no EDS spectra on the Aztek system. On examination we found 2 user-correctable issues. First, the backscatter detector was blocking part of the x-ray signal from reaching the detector. It was not in the correct orientation. Then, and this is the biggest issue, the Process Time was set to 2 and it should be on 5. Process Time 2 provides narrower peaks (energy resolution) but reduces the deadtime (count rate). The SOP lists 5 as the default position. If you change it, please return to 5 when your work is complete.

The EDS works fine and is ready to use.
