Abstract
As part of the US LHC program to develop high gradient superconducting quad rupoles for the LHC interaction regions, a series of 2 meter long model mag nets has been built and tested at Fermilab. This R&D program was used to re fine the mechanical and magnetic design, optimize fabrication and assembly tooling and ensure adequate quench performance. The final design, fabricati on, and assembly procedures developed in this program have produced magnets which meet the LHC requirements of operating at 215 T/m with excellent mag netic field harmonics. This paper summarizes the test results of the last f ive model magnets, including quench tests over several thermal cycles, and excitation current ramp rate and temperature dependence studies.
