Specification • Integrated field 5.0 Tm. Magne=c length <1.79m. Magnet < 2 m long • Mul=poles design =<10 units? at all opera=onal fields and configura=ons. Apertures independent.
• Aperture: 105 mm. • Beam distance: 188/194 mm. • Faster Ramps rates ~100 s is the target value ! • Opera=ng current < 600 A). (450 to 500 A) • Dose of 5 to 10 MGy so we need a radia=on hard insula=on.

Reducing current from 434 A to 200A would reduce power supply cost by approximately 40KCHF x 16= 640 KCHF. However interlayer voltage moves into problema=c area above insula=on nominal values. 600A we save 4.4 Mchf over the 4 KA design ( just PSU saving)

Quench model taking into account the thermal propaga=on along wire and radially: turn to turn, and layer to layer.
Conclusion: we need to select 600 A power supply op=on running at approximately 450 A

the D2 outer iron yoke profile is an ellipse whose Xmax is 624 and Ymax 554 mm (see above). The outer shell has not been fixed yet, but it will likely be an ellip=cal "skin" around the yoke ~5 mm thick.
To summarise, the available external diameters for the cold masses we have or will have are: • 570mm used for the main dipole and MBH 11T dipole • 495mm used for the inser=on cold masses (series 600 also called MQM or
MQY cold masses) • 630mm that will be used for the HL-‐LHC triplet quadrupole cold masses

: Desired Iopp at given B and T , 550A @ 1.9K Max magnetization at given B and T Desired Cu fraction 4:1 to 6:1 Desired wire size not yet decides Desired wire shape (round or rectangular) not yet decides need test but 1st choice rectangular Unit length for series (and for proto) 3070 m / 10 +10% = 350 to 400 m individual wires ? Total quantity for series (and for proto) 3230 m / aperture x 2 x 4 = ~26km models and prototypes
3230 m/ Aperture x 2 x 20 +20 % = ~ 155 km ? Wire cost guess 0.8 to 1 euros/m = 156 to 200 k euros. Desired dates for availability of wire (and associated quantities)
models : Jan 2016 (so use out wire type 3 in stock) prototypes: April 2016 production : Jan 2017
