MANUFACTURING STATUS
Price inquiry for the structure launched in September 2011
The order placed in November 2011 has been split between 3 European companies Cold-mass to Aratz (Spain) Coil-pack (& dummy coil) to Boessenkool (Netherland) Axial compression system to Mectalent (Finland)
All detailed drawings have been approved in December 2011
Delivery of all components is expected by middle of April 2012

2 facing surfaces of the coils will be mold released Gap between coils will be filled with 0.9 mm fiber glass
cloth Impregnation of the fiber glass using the coils as cavity This will guarantee a perfect contact between the 2 coils This technique will allow to separate the coils in case of
failure of one coil

ALUMINUM DUMMY COIL ASSEMBLY
The first mechanical assembly will be performed using aluminum blocks replacing the real coils
This will qualify the support structure, the assembly and loading procedure and validate the FEM
The aluminum dummy coils will be instrumented with strain gauges in the aperture
The way to cool-down the structure to 77 K in LN2 is under investigation
