     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.
