Shell-based support structures for Nb$_{3}$Sn accelerator quadrupole magnets
/ Ferracin, P (LBNL, Berkeley)
Shell-based support structures are being fabricated and tested as part of the development of large-aperture Nb$_{3}$Sn superconducting quadrupoles for future upgrades of the LHC Interaction Regions. These structures utilize water pressurized bladders for room-temperature pre-load control, and rely on a pre-tensioned aluminum shell to deliver a substantial part of the coil pre-stress during cooldown.
