Abstract

Individually powered twin-aperture superconducting quadrupoles with a coil bore of 70 mm will be installed in certain areas of the LHC insertions where increased geometrical acceptance is required. A 1-m twin-aperture model of the quadrupole, featuring a four-layer coil with a nominal gradient of 160 T/m at 4.5 K, has been built and tested. In this report we present the quench performance of the magnet, and discuss the results of the quench protection studies and magnetic field measurements
