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
