Test and Analysis of Technology Quadrupole Shell (TQS) Magnet Models for LARP

Test results are reported on four quadrupole magnet model tests (TQS01a, TQS01b, TQS01c, TQS02) in support of the development of a large-aperture Nb$_3$Sn superconducting quadrupole for the US LHC Accelerator Research Program (LARP). All four magnet assemblies used key and bladder technology to comp...

Sumario:Test results are reported on four quadrupole magnet model tests (TQS01a, TQS01b, TQS01c, TQS02) in support of the development of a large-aperture Nb$_3$Sn superconducting quadrupole for the US LHC Accelerator Research Program (LARP). All four magnet assemblies used key and bladder technology to compress and support the coils within an iron yoke and an aluminum shell. The first three models tested different magnet assemblies of several coils, having MJR conductor, and gapped segmented bronze pole-islands. TQS02's coils utilized improved (RRP) conductor, and addressed TQS01's quench-training pattern, by utilizing titanium alloy (TiAl6V4) pole-islands, with no axial gaps during reaction. This paper summarizes the assembly, cool-down and performance of TQS01a, TQS01b, TQS01c, and TQS02 and compares measurements with design expectations.
