Notes and to-do lists for the solenoid coil tests this summer and fall.

Test Area

• Notes:
  • Wayne is designing overall layout.
  • Area in the test lab is 20'6" x 25'9", currently filled with coils and coil parts.
  • May be able to get space in adjacent areas (QWeak construction and SRF cavity storage areas).
  • May need extra space for large power supply (6' x 5') and switch, and to avoid placing controls racks in large B field.
  • Must maintain clear areas around racks and power supply, and cannot block pedestrian walkways.
  • Platform is 172" x 160", cryo can will sit on top.
  • Platform must be removed to swap coils, and all connections to it must be broken.
  • Area has two cranes, but need both (and spreader bar) to lift heaviest yoke (45 tons).
  • Need come-alongs and anchors to move yokes and coils along rails.
  • Some areas will need to be roped off due to high B fields (> 5 Gauss, for pacemakers)

• To Do:
  • Look into getting space in adjacent areas - George
  • Look into possibility of locating computer in control room - Elliott
  • Distribute Floyd's B field map for single coil, no cladding - George
  • Determine location of all components - Wayne
  • Investigate sensitivity of electronic equipment to B fields - Elliott
  • Find spreader bar - George
  • Determine areas to be roped off due to high B field - Floyd, George

Infrastructure

• Notes:
  • Platform borrowed from Hall A.
  • Rails currently at IU.
  • Have or can borrow all material moving equipment, or will contract out to rigging firm.
  • Have or can borrow all tools needed.
  • Controls racks coming from Randy H or from computer center.

• To Do:
  • Produce overall system diagram - George
  • Design structures and mechanical components, route cables and cryo piping, etc. - Wayne
  • Arrange for piping designer - George
    • Design piping to vent N2.
    • Design warm and cold He supply/return systems, LN2 supply system.
  • Retrieve rails from IU - ?
  • Get three racks from Randy H or from CC - Mark S and Elliott W
  • Determine cryogen supply/return needs - George
  • Arrange for cryogen supply/return with Dana Arenius (and Kelly Dixon?)- George and Elliott

Components

• Notes:

• To Do:
  • Order cryo can - George
  • Verify all cryo transfer lines and U-tubes are available on site - Mark S
  • Verify we can borrow heat exchanger from Hall A - George
  • Get heat exchanger - Mark S
  • Order remaining piping - ?

Programming

• Notes:
  • Mark W will do all programming.
  • Can borrow lots of code from Steve Lassiter and co.
  • Single computer will perform all control and monitoring tasks.

• To Do:
  • Install new memory in controls computer - Elliott and Mark W
  • Purchase new software licenses - Elliott
  • Install all software on controls computer - Mark W
  • Borrow code from Steve Lassiter - Mark W

Staging

• Notes:
  • Will instrument controls racks in F117, then move to Test Lab.
  • Will instrument for final 4-coil system.

• To Do:
  • Rearrange F117 - Mark S and Beni
  • Get and move 3 racks into F117 - Mark S

Reviews

• Notes:
  • Micro-review of PLC vendor choice completed, waiting for report.
  • Need cryo, electrical, mechanical, and operations reviews.

• To Do:
  • Write thank-you letter to Jonathan Creel and Omar Garza for participating in PLC vendor review - Elliott
  • Write appropriate documentation - George, Mark S, Wayne and Elliott
  • Set up all reviews - George and Elliott

Construction

• Notes:
  • Do we have enough manpower?

• To Do:

Coil Tests

• Notes:
  • Verify correct operation of all coils.
  • Determine stresses up to full current (1600 A).
  • Will take about one month per coil.
  • Will take a few days to cool down a single coil.

• To Do:
  • Create test plan - George
