== Last Week's To-Do List ==
* ME providing CAD models to look at and compare w/ 2D dimensioned layout [[media:beamlinelayoutmarch26.pdf]]
:: Now on [https://jeffersonlab-my.sharepoint.com/:f:/g/personal/grames_jlab_org/EhXqNtq16CBNt4JzMmy4T1ABNsJ15YGBFTQkkMenD_ommQ 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 [https://vacgen.com/linear-drive-70mm-od-75mm-z-m6-tapped-stepper-encoder], 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.
::[[Media:mag_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?
