Abstract
As part of an R&D effort to demonstrate that Nb3Sn is a viable option for the upgrade of the CERN-LHC interaction region magnets the US-LARP collaboration launched in 2008 the High-field Quadrupole (HQ) program. A total of 26 HQ coils were fabricated in three successive production series (HQ01, HQ02 and HQ03), each followed by intensive tests of the coils in a magnet. In April2014 the second generation of HQ coils (HQ02) was tested in a quadrupole structure where it reached 94% of the current short sample at 1.9 K. Following this success a third series of coils were fabricated (HQ03) with the goal of demonstrating reproducibility in the coil fabrication process and to remedy the fabrication issues that led to discarding several HQ02 coils. HQ03 coils are planned to be tested in 2014.
