QXF Cable Winding Test and End Parts Design
QXF Cable Winding Test and End Parts Design Miao Yu Fermilab 11/15/2012 The Hi. Lumi LHC Design Study (a sub-system of HL-LHC) is co-funded by the European Commission within the Framework Programme 7 Capacities Specific Programme, Grant Agreement 284404.
IL RE Pole Preliminary Design • Based on QXF cross-section design 3 • BEND program • Import the output (a group of points) of BEND to CAD software • Create ruling lines and the surface, and then generate the parts
QXF Cable Winding Test Setup L 1 RE Pole Mandrel Spacer HQ/LHQ Winding Mandrel • Two IL RE pole pieces (rapid prototype) • Total winding length ~0. 77 m
End Parts Design Plan • Once the cross-section is chosen, Fermilab will design end parts using BEND. • Fermilab and CERN will share the parameters. • The parts will be fabricated by laser sintering. • Practice coil will be fabricated (LQXF). • The “BEND” end parts will be compared with the “ROXIE” end parts.
