Abstract
In the frame of the high-luminosity upgrade project (HL-LHC) at CERN, a double aperture, independently powered, family of beam orbit corrector magnets will be installed close to the two main LHC experiments Atlas and CMS. These 2.6 T magnets, built using a canted cos-theta design. This paper describes the development of the prototype, full size 2-m-long magnets. We first focus on design and assembly techniques: from coil winding using a CNC machined aluminium former to impregnation, layer-jump, quench protection, and yoke assembly. We then present the power test results at 1.9 K: training, field quality and protection.
Highlights
The Large Hadron Collider (LHC) has been the largest and most powerful particle accelerator in the world since it became operational in 2009
We plan to re-test the wire after insulation, to see if the heating that bonds the insulation to the wire will degrade the its critical current (Ic) values, we saw a 5 to 7 % reduction with the CERN wire after heating to bond the insulation
A twin aperture full size prototype has been constructed, tested and has achieved nominal performance according to specification
Summary
