Last Week's To-Do List

Now on Link to AIPINJ OneDrive folder, then they're in the "20.03.26 Beamline Screen Shots".
MFX before A1 moves further upstream on spool
A2 is now a cube, instead of a cross
harp before A2 is rotated 45 deg CW looking downstream, there is a viewer on it too
  • Danny working w/ MDC so their BPM shop drawings match his submitted drawing
the BPM cans from MDC are due to ship april 13th.
  • Joe finding status of BPM feed through delivery
Requested date is 4/25
the BPM antennae are due to ship: a quantity of 7 in three weeks, the balance on may 7th.
  • ME working on finishing solenoid fixture designs
  • Marcy checking on top hat configuration for Y-chamber media:200326_viewer shield.pdf
  • ME can go ahead order spools for Sections 2 & 3
  • Shaun add "stay clear" zone of camera to model
Joe measured 4" dia x 6" length tube
  • Danny check with Milhous & Jlab people for dipole design
Yes, nice examples. Jay OK. Joe OK. Req submitted & signed
  • Reza talk out with Curt or Rick about power needed and controls desired
  • DP can, will new $$$ NEG's fit or not
  • Marcy get quotes on A1/A2 cubes and 6-way cross w/ R-R
  • Decide on A1 media:200326_aperture 1.pdf insert depths
  • Finalize A2 media:200326_aperture 2.pdf in layout, need to wind coils now too
  • Scott figure out how to control [1], set limits, positions, use encoder w/ stac5
ordered a stac5
  • Let Joe Meyers know what color to paint solenoids
Lime
  • Riad - will magnetic field of first coil reach photocathode? will it affect solenoids?
Field map: media:BH_Haimson_Coils.xlsx => Field extends to 8 cm from center of magnet.
  • Carlos/Gabriel evaluate model for smaller gap Wien filter
  • Lakshmi status of PSS coil models
  • Dennis turn elegant model values into expected magnet currents.
