March 20, 2020 - ME/INJ/CIS

Meeting Info

Friday 3/20 @ 10am by bluejeans: https://jlab.bluejeans.com/553225778

Agenda

How to move forward?

• 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)

CIS jobs

• identify source for all components needed
• complete purchase reqs
• testing the Wien filter
• building up the NEG tube in a few weeks

INJ/CASA jobs

• help finalize final layout
• evaluate layout w/ simulations to list operational settings (solenoids, quads, prebuncher), Wien's off and on

Last week's punchlist

ME

• 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

INJ

• 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? => Riad, can you please look into this

CIS

• Matt - Lubricate the stepper motors => added to summer work plans
• Matt - Order spare right angle values => Done, 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)
