March 20, 2020 - ME/INJ/CIS

Meeting Info

Let's work through our 'jobs' and see what work can be done at home, what cannot

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)

list/identify all components needed
complete purchase reqs
the Wien filter Wien filter link
- Media:Update from Carlos for AIPINJ meeting March 20 2020.pptx
A1 linear vacuum assembly (motor + encoder or limit switches)
BPM can assembly
NEG coating spools/BPM's

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

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
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? => 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?
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
