1. Analytical Cost Model (16 T dipole)
T. Martínez, J. Munilla, F. Toral - CIEMAT
Progress Meeting #, October. 13th, 2016

2. Preliminary main cost drivers
Manufacturing of main components (strict fabrication tolerances):
End spacers
Cu-Alloy wedges
Iron yoke laminations
Iron pads
Conductor and wedges insulation.
Impregnation
Ground insulation
Plasma coating
Quench Heaters (Tiina Salmi talk) 2

3. Status of the analytical study
End Spacers:
Reference price (11T): 1.100€ (end saddle)+4.200€=5.300€ per coil
Estimation for 16T :
Inner layers: 4.416,6€
Outer layers: 9.169€
2 coils and 2 apertures: ,6€ per magnet
Scaling by volume 3

4. Status of the analytical study
Cu-Alloy Wedges: 4

5. Status of the analytical study
Cu-Alloy Wedges:
Quotation for these 2 different profiles of wedges has been asked to Luvata and Buntmetall
One dipole cold mass contains approximately 560 meters of copper wedges of each different profile. The wedges shall be delivered in 3500 mm long pieces. Consequently in one cold mass there are 160 copper wedges pieces of each profile.
Luvata proposal:
Half length: 1750 mm long pieces
Change in tolerances:
thickness +/- 0,03 mm
width +0,04 /-0,06  mm 5

6. Status of the analytical study
Iron yoke and iron pad laminations (ARMCO):
Manufacturing tolerances still under discussion
Laminations of 5,8 mm could be a good starting point
Meeting organized with AK steel next Wednesday
Conductor and Wedges Insulation:
Experts form CERN has been contacted
Impregnation:
CTD-101K will be used
Price will be required
Ground insulation: price for Kapton HN 125 microns has been required
(500 km lenght/ 250 mm width) 6

7. Status of the analytical study
Plasma Coating:
2000€ per set of 14 parts for the plasma coating of the MQXF (1 coil)
Scaling by areas as Etienne Rochepault has suggested:
MQXF aperture: 150 mm
Dipole/quadrupole:
4 layers/2 layers
2 coils per magnet
2 apertures
Final price: € per magnet
