       1. Want Secretary, may require delay until January
     iv. Students – new graphs to show strong need to start running, more operations
       1. 200 technically still working on PhDs
     v. Space issues:
       1. SRF/LCLS II has to rework two older modules
         a. Need 6 months….may need new corridor through test lab high bay
         b. Looking at space organization
         c. SRF will do the move if we want
       2. Space in EEL will be added to Physics
         a. Gain EEL #122 (?) – old polarized source lab, electronics group to move there
     vi. JLEIC accelerator and engineering presentations for pCDR – every week to end of year
       1. Also noon chat lunches
       2. pCDR ~ summer, fall
       3. Femtography request to state, ~ $500k (imaging center like INT, ECT,…) Would really need ~ $2M/year, 
          but need something to get started
         a. Will find out in few months
       4. Streaming readout @ MIT workshop – late January
       5. POETIC & DIS coming up
     vii. Capital Equipment for out years….
       1. Difficult because we’re not running
       2. Redirect towards something like MOLLER, SoLID,….
       3. 3He ok, some fast electronics…. - Prioritize! (useful for >1 hall higher)
       4. Can look again later and reshuffle if necessary
   b. Hall A
     i. Tritium is in the Hall!

         lock-up

2. Robin Wines
   a. SBS
     i. Continue on ECal drawings
     ii. Filing assembly drawings
     iii. Checking HCal support drawings
   b. Tritium
     i. Evaluating various correctors for use in shielding beamline from fields in Fall 2018 run
   c. PREX2/CREX
     i. Design of vacuum chambers
     ii. Collimator/sieve removal and shielding supports

3. Jessie Butler
   a. Worked on LQ3 and left dipole pressure sensors and distribution can flow differential flow meter (working 
      to improve on accuracy for troubleshooting purposes)
   b. Ordered parts for making parts for SBS exit beamline shielding HCal module assembly
   c. Completed test for aluminum welding and continued to clean-up and organize tools and equipment in
