We believe that we have resolved the chamber pumpdown problem
around midnight. We have noticed a significantly faster pumpdown during
the day since we cleaned the heavy polymer build-up off the baseplate
and the hexode pedestal. Prior to the clean, it took about 5.5
minutesfor the process to start after the RUN button is pressed. After
the clean, It took about 2.5 min. Now we need users to report on the
systems performance around midnight.
