Last Week's To-Do List

• Lakshmi model of longer rectangular PSS kicker magnet on spool

Last Week's To-Do List

• ME providing CAD models to look at and compare w/ 2D dimensioned layout media:beamlinelayoutmarch26.pdf

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.

Using the 2020-03-26 layout: Media:magnet_currents.ods

• Alicia show simulations of beams, evaluate layout for transmission and settings needed
• Joe - is the distance from MFG-A to upstream steering coil sufficient?
• Previous to-do list...https://wiki.jlab.org/ciswiki/index.php/March_20,_2020_-_ME/INJ/CIS
