  * Janet Prater is retiring at the end of June
      o Stephanie will take up her duties
  * Lab is in Medcon 4 now
      o allowed to have 1/2 of personnel on site
      o those that can work remotely should continue to do so
      o one may be asked to work on-site by one's supervisor
  * Budget: president's budget is out
      o 10% increase in nuclear physics
      o corresponds to 30 weeks of running
  * KLF beamline design has started
      o initial focus on collimator cave equipment
  * new staff position
      o committee selected 3 candidates
      o emphasis on data analysis, especially partial wave analysis
      o another position may open up soon: send ideas for needed skills
        for such a candidate to Eugene


    Activities in the Hall, Tim

  * FCAL darkroom almost ready for light-tightening
  * CPP gas for test in EEL ready to go
  * Mods to platform for CPP stand underway in Hall
  * Stand for CPP complete and will be delivered tomorrow
  * four MWPC for CPP were delivered to the EEL
  * working with Keith Harding on KLF design
  * helium beampipe for PrimEx almost complete, some testing in TEDF to
    be done


    Other Items

  * Eugene: DIRC mirrors are being remade, not need for upcoming run
      o Tim: mirrors will be stored in the boxes without water, other
        than for possible testing.
  * Patrizia: when will testing of MWPCs begin?
      o Beni: as soon as the OSP is approved, probably in two weeks
  * Eugene: mods to PS for the test set-up contemplated
      o GEMs in from of North[?] arm, project with UVA
      o extend energy range to 3 to 10 GeV
      o GEM detector 40 cm × 5 cm
      o will run independent DAQ, no need for tagger read-out
      o Tim vertical stage ordered for downstream detector support
      o there will be 2 movable stages for detectors under test
  * Sascha: survey of beam pipe at FCAL now that it is exposed since the
    darkroom is dis-assembled?
      o Tim: will try to schedule it
  * Sascha: preparations for FCAL II
      o procurement of crystals an issue
      o module design in good shape
          + 30 have been fabricated
          + Chris Allen doing brazing on the brass strips
      o two undergraduates would be nice for assembly tasks
      o detector group involvement would be useful, will send request to
        Patrizia
      o ready to start production of modules
      o focus on the CompCal at present
