Quench characteristics of superconducting magnets of low energy beam line for FAIR facility

Quench analysis of quadrupole and sextupole of FAIR magnet has been carried out through OPERA Quench solver. The peak temperature and maximum voltage generation within the coil have been evaluated. If the peak temperature and voltage exceed the certain limit, it will damage the electrical integrity of insulation and even melt down the conductor. The various protection schemes have been used to reduce the peak temperature and voltage drop to ascertain permissible limit for safe and trouble free operation of the magnet. The role of quench back on transient parameters like current and temperature has also been carried out in this paper.
