  • Align laser to photocathode, using retro and QE (8/5) [Shukui]
  • Gun rebuild wiki


DC Power:

  • Trims:
    1. Trim magnets near gun re-cabled.
    2. Wastewater beam line trims cabled up.
    3. Trim magnets near FC#3: 401H/V (completed) & 501H/V correctors + 501 quad

    2. Reconnect IYGM401 (formerly ITV, now YAG)
    3. Drag cable and connect IYGM603 and IYGM603 (appropriated from HDice line, swapped ITV > YAG).
    4. Brian Freeman available for adViewer work for video camera for ITVM604A? Dome focusing still required...

Wire Scanners [Delacruz / Poelker]

  • IHAM703 Status (Scanner swapped out)

Chopper Controls (Windham/Lu)

  • STAC5 Controls replacement (done)
  • Encoder mapping (/10)
  • Controls transparent to user

Chopper Controls (Windham/Lu)

BPMs (Windham / Hesse / McCaughan)

  • Install new BPMs on line (completed)
  • Map DR receivers to appropriate chassis (completed)
  • Correct all naming and controls issues
  • Re-label locally.

Faraday Cups (Francis)

  • FC cups 3 & 4 installed in new locations and under vacuum
  • Cables / air lines /etc pulled to new locations and installed
  • Connections removed for shielding installation per RCG.


BCM

  • BCM project software integration under way between Musson/Seaton and Sue Witherspoon



RF:

  1. 6GHz > 1.5GHz Down-converter installed for bunch length system

Vacuum:


SSG:

  1. BLM locations being set 7/21 following this meeting
  2. FSD inputs for magnet and BCM being prepared

ME / Installation:

  1. Pb stacked; RCG required modification due to permanent shielding req delay.
  2. New designs for FC3 and FC4 with a great many thanks to Shaun for the design work and John/Xi for Pb arrangement and table construction!
  3. Songsheet being updated by Shaun; be sure to let him know when changes are made!
  4. Status of permanent shielding purchase?

Experiment:

  • COO/ESAD/RSAD prepared; committee response in progress.

Other:

Still to do:

  • Add Mu metal over bellows on wastewater line.


Next Week:

  • Mount bottle rack in Labyrinth (Staged); remove gas bottles to rack.
  • Unistrut mounting for cables - Neal will do when available
  • Engineering work on beam line starting

2 weeks:

  • Pull Heliax from Spectrum analyzer/Control room >> Buncher
  • 4th terminal system in Control room under assembly/rebuild
  • Items from To-do list...

Engineering Other business
