      o represents 45% of staff
  * time-sheets are due early this time due to the end of the fiscal year
  * performance appraisal cycle starts Oct. 8
  * IUTF achieved 1 nA current at 5 MeV for the first time
      o long-standing plan to use it to test the HD Ice target
  * EIC is moving forward
      o virtual groundbreaking held
          + "attended" by JLab senior management
      o yellow reports due soon
          + how to justify a second interaction point
      o need for 1-11 GeV electron test beams
          + Hall D complex is ideal
          + many issues to resolve
  * Lab budget on a continuing resolution
      o research money has not increased; solution being worked on
  * Hall D budget
      o PRs are in saturating all available funds
      o hopefully all will be obligated this FY or funds may disappear

      o being developed in Hall C
      o 15 mm gap for photon beam[?]
      o Todd Satogata: focusing not an issue
  * Igor Strakovsky working on the K_L target
  * original proposal: 64 ns bunch separation
      o 128 ns separation: discussions underway
      o bunch charge density an issue

      o funding discussion with Eugene to be had soon
  * option: refurbish Hall D FROST target
      o Chris not enthusiastic
      o leak in that device, never fixed
  * cooling power an issue


    CPP, Elton

  * need help with implementation of trigger
      o summer run: test run with random trigger
      o data analyzed to estimate rates
  * next step: implement trigger in hardware
      o requires involvement of Sascha and Fast Electronics
  * run scheduled for 2022
      o but these things take time
  * mechanical design and construction on a good track
