QXF coil radius for reaction and impregnation fixture

QXF coil radius for reaction and impregnation fixture P. Ferracin 20 June, 2013

QXF coil aperture • Rin_ins-cable = 75. 000 mm • at 293 K without pre-load – Goal • Decouple definition of coil inner radius from – mechanical computation – cool-down estimated – possible additional layer of insulation, etc. Paolo Ferracin 20/06/2013 2

Input for tooling design Nominal cable (First iteration): 18. 150 mm – Rin_ins-cable = 75. 000 mm – Bare cable width after reaction • 18. 150*1. 02 = 18. 513 mm – Cable insulation • 0. 150 mm – Inter-layer insulation • 0. 500 mm – Rout_ins-cable_layer 1 = 93. 813 mm – Rout_ins-cable_layer 2 = 113. 126 mm Paolo Ferracin 20/06/2013 3

Input for tooling design Narrower cable: 17. 800 mm – Rin_ins-cable = 75. 000 mm – Bare cable width after reaction • 17. 800*1. 02 = 18. 156 mm – Cable insulation • 0. 150 mm – Inter-layer insulation • 0. 500 mm – Rout_ins-cable_layer 1 = 93. 456 mm – Rout_ins-cable_layer 2 = 112. 412 mm Paolo Ferracin 20/06/2013 4

Input for tooling design Wider cable: 18. 400 mm – Rin_ins-cable = 75. 000 mm – Bare cable width after reaction • 18. 400*1. 02 = 18. 768 mm – Cable insulation • 0. 150 mm – Inter-layer insulation • 0. 500 mm – Rout_ins-cable_layer 1 = 94. 068 mm – Rout_ins-cable_layer 2 = 113. 636 mm Paolo Ferracin 20/06/2013 5

Range of coil radius variations for tooling • Coil OR – Minimum • Rout_ins-cable_layer 1 = 93. 456 mm • Rout_ins-cable_layer 2 = 112. 412 mm – Nominal • Rout_ins-cable_layer 1 = 93. 813 mm • Rout_ins-cable_layer 2 = 113. 126 mm – Maximum • Rout_ins-cable_layer 1 = 94. 068 mm • Rout_ins-cable_layer 2 = 113. 636 mm Paolo Ferracin 20/06/2013 6
