        1. $7M/year for 2 years
        2. $1.5M from JLab, $3M fron BNL,…”taxes”
        3. Looking at what makes sense to propose
     v. Reshuffle space in test lab, TEDF, ESB to accommodate LCLS-II rework

   c. Finish recovering the cryogenic system following the ESR crash that happened the previous weekend
   d. Help move L-HRS into 17 degree position for the start of run
   e. Completed the pressure gage change out of both Q1 magnets and re-pressurized the LCW system and bought 
      the magnets back online for testing
   f. Helped move BigBite lead crystals from Test Lab to TEDF

4. Jack Segal
   a. Spectrometer (HRS-L) will NOT move remotely until January, can move locally

5. Run Coordinator – Douglas Higinbotham
   a. Target operator training for Tritium: review slides with approved mentor, MUST TAKE to be operator!
