- Let's work through our 'jobs' and see what work can be done at home, what cannot
- 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
- list/identify all components needed
- complete purchase reqs
- the Wien filter
- A1 linear vacuum assembly (motor + encoder or limit switches)
- BPM can assembly
- NEG coating spools/BPM's
- INJ/CASA jobs
- help finalize final layout
- evaluate layout w/ simulations to list operational settings (solenoids, quads, prebuncher), Wien's off and on
Last Meeting's Punchlist
- Danny - Will Frank Marhauser model the BPM design? => Frank said he checked this
- Alicia - Show a Haimson corrector on spool downstream of first solenoid
- Joe - Please show UITF style camera assembly on viewer crosses
- 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)
- Alicia - please swap harp w/ valve on last girder before chopper
- Reza - please put A2 on a cube as well, w/ same type of steering coils
- Danny - Does A1 full retract? => 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?
- 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
