Present: Alexei, Jim, Flemming, Yuri, Gene, and myself == Hardware — used access to tune sensor for air flow — cathode dropped yesterday during the storm — may not be due to the flow sensor itself? — want to count beam dumps before and after

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


== Hardware
— used access to tune sensor for air flow
— cathode dropped yesterday during the storm
— may not be due to the flow sensor itself?
— want to count beam dumps before and after kicker repair
— RHIC has experienced more uncontrolled beam loss since repair
— maybe due to other changes made by control after repair? timing changes?
— now tuning drift velocity

== Electronics
— still the usual losses and repairs of RDOs and FEEs ((usual 15% dead on average)
— one TPX sector masked out


== Software
— increased stats by factor 10 in transverse diffusion work 
— updating hit errors for DAQ5000 work
— yesterday noticed drift velocity drop in lasers
— was confirmed by additional laser runs
— Alexei still tuning DV as mentioned above

== AOB
— Results of PAC suggest a possibility that we may run another 12 weeks
— open question about any systems that might not survive an additional 12 weeks
— answer from group seems to be no (we have enough methane until ~20th of Dec.)


Best Regards,
  Richard
