Present: Alexei, Jim, Flemming, Gene, and myself


== Hardware
— will tune east laser today during maintanence window
— shift beam a little for more illumination

== Electronics
— still the usual losses and repairs of RDOs and FEEs
— seems Tonko has removed most of the problematic ones
— some still have dead times that rise above the expected dead times
— will ask crews to identify which sectors are causing it
— can then make a note of the specific sector and make it easier to find
— the problem is intermittent, showing up every few days or so
— problem disappears if run is stopped and restarted


== Software
— nothing new reported this week


== AOB
— Crew should do half-field cosmics if there are extended down times
— should also plan for some cosmics with full field after the end of run
— currently, only thing mentioned in planning is extra half-field if not enough is taken during the run


Best Regards,
  Richard
