March 12, 2020 - ME/INJ/CIS

Mechanical

• What is the bellows type count, how may 3" and 3.5"?
• Chris, do you have all as-founds you need?
• Use C channel everywhere and move pedestals ok?

Anthony says yes, do it

• Carlos, send Shaun Wien feedthrough p/n
• SS or Al brackets?

Use Al, now all 7-3/4" girder to beam line, girder holes whereever imagine support

• NEG chambers

Detail Y- 10" flange, NEG's here

Flip DP for IP beam left, modify for new NEG's?

• Laser vacuum window?

Caryn started evaluating

Show layout of laser room, outrigger box, laser table

Shukui, tight, how to fit optics, inside laser room?

• 2I spools?

ME will order, need in time to a) weld capture solenoid, b) NEG coat

• New BPM's

Design done, feedthroughs ordered, waiting on req to MDC

• Solenoid fixtures?
• What is p/n for the 25S IP?
• Viewer top-hats

What is position when retracted for Y/Laser vs. crosses?

How many spares, do we need more or different?

Magnets

• Dipole

Emerson backed out, Milhous quoting round/square, Lakshimi working on Jay's AT design

• Soleonids

Joe M. what is status?

• Quads

Have 3 QW, Mike testing 2 spare QW quads (capture on welded cross)

• Correctors

Joe G make tally

• Wien

Technicoil getting ready to wind

• PSS Kicker

Met w/ Jerry, Lakshimi working on upgraded kicker to move 200 keV beam 1cm @ 30 cm w < 200 mA (March 9 layout)

High Voltage

• status of SS shed? (flange degased, ceramic welded, electrode cut, electrode polish, electrode mounted, fiducialize)
• status of Wien high voltage?

Orders

• Bellows - waiting on final count
• Right angle valves - we have 5 or 6, should be ok?
• Gun 10" flange - signed req for (2)
• Order 10 kV feedthroughs
• BPM feedthroughs - ordered
• BPM cans - waiting on req to MDC

Controls

• Chris, what cameras will you use, will they fit?
• Mark/Dave, do you have a plan for 2500W solid state chopper amps?
• Mark/Dave, do you have a plan for Brock prebuncher cavity/amp?
• Omar, do you have BPM channel?

Yes!

• Remove hall probe
• Wien HV controls

status of prototype test at UITF?

layout in ISB racks?

drops/penetrations?

controls screens?

• Wien PS

layout in ISB racks?

drops?

Modelers

• Is the March 9th layout ok?
• Is the harp location OK for solenoid scans?
• Should a viewer remain at the harp location, should this be a YAG?
• Where else should YAG's go?
• Can a YAG go at the laser screen, I don't think so?
• Is the beam envelope OK for ways we run spin rotators?

What are the currents and/or B's for the solenoids and quads?

• What are the power levels for existing or Brock prebuncher cavities, for 130 or 200 keV locations?
• Is distance from MFG1I04A to upstream corrector far enough? or move MFG1I04A downstream, how far?

Jay is running cases

• Is the corrector/bpm downstream A1 useful?

Commissioning

• Plan for May gun work?
• BPM job

Receive can/feedthroughs

Clean

Degas

Coat

Check feedthroughs, assemble feedthroughs

Leak check cans

electrical measurement

serialize

report K's and center
