Engineering > Design Reviews  WBS 19 Coil Tolerance, Trim Coil Requirements and Material Material in the Test Cell
Review Title Coil Tolerance, Trim Coil Requirements and Magnetic Material in the Test Cell Peer Review
Date 21 April 2004
Cognizant Engineer Art Brooks
Responsible Line Manager Brad Nelson
Review Board Chairperson Wayne Reiersen
Review Board Members Mike Zarnstorff, Dave Williamson, Jim Chrzanowski, Mike Kalish
Invited Attendees Hutch Neilson, Steve Hirshman, Dennis Strickler, Chang Jun, Phil  Heitzenroeder
Other Attendees Tom Brown, Mike Viola, Steve Raftopoulos, Mike Cole

1) Are the bases for the coil tolerance requirements complete?

Field errors from coil imperfections, errors from fixed ferromagnetic material in building.

2) Are the tolerance requirements well defined?

for modular coils,  TF and PF coils and for trim coils.

3) Are the trim coil performance requirements (no., current, dl/dt, etc.) well defined?

4) Are additional analyses underway to investigate relaxation of tolerances, if needed, to address: coil deflections from cool down and magnetic loads, magnetic material in coil structures, coil position optimization.

5) Are additional analyses planned to address final coil design, including actual crossover and lead geometry and location?
