5. MQXF magnet design 18/09/2014 Paolo Ferracin5

6. Axial loading and connection box update RE: threaded end plate (50 mm thick) – Axial pre-loading on LE 18/09/2014 Paolo Ferracin6

7. Axial loading and connection box update 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 18/09/2014 Paolo Ferracin7

8. Axial loading and connection box update Removal of the axial pre-loading system – Still only 1 nut used 18/09/2014 Paolo Ferracin8

9. Axial loading and connection box update Status before connection box – 2 nut but no rod extension – Connection box will go on top (see later) 18/09/2014 Paolo Ferracin9

10. Axial loading and connection box update Hard (impossible?) to stay within bushing or nuts or rods 18/09/2014 Paolo Ferracin10

11. Axial loading and connection box update Support plate 18/09/2014 Paolo Ferracin11

12. Axial loading and connection box update Instrumentation plate – Wires coming out parallel to the leads 18/09/2014 Paolo Ferracin12

13. Axial loading and connection box update 2 connections 18/09/2014 Paolo Ferracin13

14. Axial loading and connection box update Third connection 18/09/2014 Paolo Ferracin14

17. MQXF magnet design 18/09/2014 Paolo Ferracin17 Magnetic length of short model

18. MQXF magnet design 18/09/2014 Paolo Ferracin18 From magnetic length to end of magnet (end-plate + connection box) – Connection side: 510 mm – Non-connection side: 214 mm

19. Q1 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) 18/09/2014 Paolo Ferracin19

20. Q2 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) 18/09/2014 Paolo Ferracin20

21. Minimum distance between Q1a and Q1b magnetic lengths 18/09/2014 Paolo Ferracin21 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 Still to be added – Lyra between yoke and connection box or pig-tail If bus-bar outside cold mass, no issue – End cover 18/09/2014 Paolo Ferracin22

23. Axial loading and connection box update Still to be added – Lyra between yoke and connection box or pig-tail If bus-bar outside cold mass, no issue – End cover 18/09/2014 Paolo Ferracin23
