Axial loading and connection box update RE: threaded end plate (50 mm thick) – Axial pre-loading on LE 18/09/2014 Paolo Ferracin6
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
Axial loading and connection box update Removal of the axial pre-loading system – Still only 1 nut used 18/09/2014 Paolo Ferracin8
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
Axial loading and connection box update Hard (impossible?) to stay within bushing or nuts or rods 18/09/2014 Paolo Ferracin10
Axial loading and connection box update Support plate 18/09/2014 Paolo Ferracin11
Axial loading and connection box update Instrumentation plate – Wires coming out parallel to the leads 18/09/2014 Paolo Ferracin12
Axial loading and connection box update 2 connections 18/09/2014 Paolo Ferracin13
Axial loading and connection box update Third connection 18/09/2014 Paolo Ferracin14
Axial loading and connection box update Top plate 18/09/2014 Paolo Ferracin15

MQXF magnet design 18/09/2014 Paolo Ferracin17 Magnetic length of short model
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
Q1 Connection side: from magnetic length to end of end-cover – =540 mm (510 mm magnetic to end of magnet in MQXF) Non-connection side: from magnetic length to Q1a-Q1b “middle point” – =250 mm (214 mm magnetic to end of magnet in MQXF) 18/09/2014 Paolo Ferracin19
Q2 Connection side: from magnetic length to end of end-cover – =559 mm (510 mm magnetic to end of magnet in MQXF) Non-connection side: from magnetic length to Q1a-Q1b “middle point” – =250 mm (214 mm magnetic to end of magnet in MQXF) 18/09/2014 Paolo Ferracin20
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: (?) = ~ 450 mm
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
