On-Going Jobs

Let's work through our 'jobs' and see what work can be done at home, what cannot
Today's work plan file media:200320_AIPINJ_Workplan.xlsx
ME jobs
  • what's the capability to work on the layout at home? and to distribute updated of models to look at? or dimensioned beamlines to use?
  • what's the list of ME tasks (design, fabrication, orders)
MAG jobs
  • PSS kicker
  • DS dipole
CIS jobs
  • help finalize final layout
  • evaluate layout w/ simulations to list operational settings (solenoids, quads, prebuncher), Wien's off and on
    • Spreadsheet with quad and solenoid settings for various Wien configurations, from elegant:


Last Meeting's Punchlist

  • Danny - Will Frank Marhauser model the BPM design? => Frank said he checked this, the BPM is quite similar to previous ones that I have modelled based on given designs
  • Alicia - Show a Haimson corrector on spool downstream of first solenoid => done
  • Joe - Please show UITF style camera assembly on viewer crosses => done
  • Joe - Do we need a different length spool piece through the two FG solenoids than exists today? =>
  • Matt - we probably need a new A1 cube (prior one modified for Brock bunchlength monitor) => reqs for new cubes
  • Alicia - please swap harp w/ valve on last girder before chopper => done
  • Reza - please put A2 on a cube as well, w/ same type of steering coils => done
  • Danny - Does A1 full retract? => Bottom edge of A1 nominal 0.475" (12mm) out of beam line media:200320_Aperture1.pdf
  • Joe - do you need 200 keV beam for any final checkout tests before we take beam line apart? =>
  • Joe - is the distance from MFG-A to upstream steering coil sufficient? =>
  • Matt - decide what power you need in different cavities/locations, work w/ RF to determine regulation needed =>
  • Riad - will magnetic field of first coil reach photocathode? will it affect solenoids? => Field map: media:BH_Haimson_Coils.xlsx
  • Joe - do we have all ion pumps and valves per model? => Marcy's first pass, but needs to see model again media:200320_ion pumps and valves.pptx
  • Matt - Lubricate the stepper motors => added to summer work plans
  • Matt - Order spare right angle values => ordered +2 in addition to existing 5 in tunnel
  • Matt - Update on Brock pre-buncher delivery plan => parts due to Jlab by early April, (many fab/testing steps, so probably delays)
  • Joe - What's dependence of spacing FG's closer? => Jay ran the models for 4 or 5 spacings
