We have had some problems with our maser. ( micro processor froze up and we had some problems getting it running again.) My thanks to Don at Allied for all his help. When we got the maser going we had to adjuste the clocks so the maser should be ok temp. wise in a couple of hours. we will continue to monitor clocks.

They also assured me that the problem was (hopefully) corrected today and should be OK for tomorrow's data. Sorry for the inconvenience this might have caused.

The Westford Maser's uproc was restarted with the time being reset and no change to stability. When the maser uproc at Algonquin froze, frequency control was affected. Control was restored approximately 1.5 hours before the start of the experiment, but there might be some frequency instability at the beginning of the experiment. The time was reset on both Masers. Except for the possible frequency instability at Algonquin, these problems should have very little effect on the Masers performance. We are investigating the cause of these processor problems.
