Mechanical Analysis and Assembly of MQYYM: A 90 mm NbTi Quadrupole Magnet Option for HL-LHC

For the HL-LHC project, a 90 mm double aperture NbTi quadrupole magnet is being developed as an option to replace the 70 mm aperture LHC quadrupole MQY. This cos2θ magnet has an operating gradient of 120 T/m at 1.9 K and a magnetic length of 3.67 m. A single aperture short model magnet with a magnet...

Descripción
Sumario:For the HL-LHC project, a 90 mm double aperture NbTi quadrupole magnet is being developed as an option to replace the 70 mm aperture LHC quadrupole MQY. This cos2θ magnet has an operating gradient of 120 T/m at 1.9 K and a magnetic length of 3.67 m. A single aperture short model magnet with a magnetic length of 1.2 m has been designed at CEA and is being manufactured in collaboration with CERN. The magnet support structure is relying on self-supporting collars. We present here the mechanical analysis along with the assembly of the short model magnet from coil fabrication and mechanical characterization to collaring and yoking.
