✦ Synopsis
This paper presents a study of the thermal eects on quench performance for several large Hadron collider (LHC) single aperture short dipole models. The analysis is based on the temperature pro®le in a superconducting magnet evaluated after a quench. Peak temperatures and temperature gradients in the magnet coil are estimated for dierent thicknesses of insulation layer between the quench heaters and the coil and dierent powering and protection parameters. The results show clear correlation between the thermo-mechanical response of the magnet and quench performance. They also display that the optimisation of the position of quench heaters can reduce the decrease of training performance caused by the coexistence of a mechanical weak region and of a local temperature rise.
