  1. MQXF length P. Ferracin Video-meeting Structure WG September 18th, 2014

  2. Coil CAD model Paolo Ferracin

  3. MQXF magnet design Paolo Ferracin • Coil • Pole alignment key (G11) • Bolted collar (Al) • Bolted pads (iron) • Masters (iron) • For bladders • Yoke (iron) • Aluminum shell • For pre-load • Stainless steel shell • LHe containment

  4. MQXF magnet design Paolo Ferracin • Coil • Pole alignment key (G11) • Bolted collar (Al) • Bolted pads (iron) • Masters (iron) • For bladders • Yoke (iron) • Aluminum shell • For pre-load • Stainless steel shell • LHe containment

  5. MQXF magnet design Paolo Ferracin

  6. Axial loading and connection box update Paolo Ferracin • RE: threaded end plate (50 mm thick) • Axial pre-loading on LE

  7. Axial loading and connection box update Paolo Ferracin • Piston support with grooves to provide space for Nb-Ti leads • Cable needs to be bent outwards • Thread for rod extensions where second nut will be placed • ~70 t provided at room temperature

  8. Axial loading and connection box update Paolo Ferracin • Removal of the axial pre-loading system • Still only 1 nut used

  9. Axial loading and connection box update Paolo Ferracin • Status before connection box • 2 nut but no rod extension • Connection box will go on top (see later)

  10. Axial loading and connection box update Paolo Ferracin Hard (impossible?) to stay within bushing or nuts or rods

  11. Axial loading and connection box update Paolo Ferracin Support plate

  12. Axial loading and connection box update Paolo Ferracin • Instrumentation plate • Wires coming out parallel to the leads

  13. Axial loading and connection box update Paolo Ferracin 2 connections

  14. Axial loading and connection box update Paolo Ferracin Third connection

  15. Axial loading and connection box update Paolo Ferracin Top plate

  16. MQXF magnet design Paolo Ferracin

  17. MQXF magnet design Magnetic length of short model Paolo Ferracin

  18. MQXF magnet design Paolo Ferracin • From magnetic length to end of magnet (end-plate + connection box) • Connection side: 510 mm • Non-connection side: 214 mm

  19. Q1 Paolo Ferracin • Connection side: from magnetic length to end of end-cover • 301.5+238.5=540 mm (510 mm magnetic to end of magnet in MQXF) • Non-connection side: from magnetic length to Q1a-Q1b “middle point” • 186.5+63.5=250 mm (214 mm magnetic to end of magnet in MQXF)

  20. Q2 Paolo Ferracin • Connection side: from magnetic length to end of end-cover • 325+234=559 mm (510 mm magnetic to end of magnet in MQXF) • Non-connection side: from magnetic length to Q1a-Q1b “middle point” • 172+78=250 mm (214 mm magnetic to end of magnet in MQXF)

  21. Minimum distance between Q1a and Q1b magnetic lengths Paolo Ferracin • From magnetic length to end of magnet (end-plate + connection box) • Non-connection side: 214 mm • Minimum distance: 214+214+22 (?) = ~ 450 mm

  22. Axial loading and connection box update Paolo Ferracin • Still to be added • Lyra • between yoke and connection box or pig-tail • If bus-bar outside cold mass, no issue • End cover

  23. Axial loading and connection box update Paolo Ferracin • Still to be added • Lyra • between yoke and connection box or pig-tail • If bus-bar outside cold mass, no issue • End cover
