Quench simulation of a 9T supercoducting solenoid magnet for VECC RIB facility beam line

It is important to evaluate the peak temperature and voltage of superconducting magnet to ensure its safe operation. If the peak temperature and voltage exceed certain limit, it will impair the electrical integrity of the insulation material or even cause a meltdown of the cable. In this paper, temperature rise, voltage drop of high field superconducting magnet for VECC RIB facility have been discussed. The results obtained from simple and approximate theoretical formulation have been compared from results obtained from simulation using a quench solver computer code OPERA. The quench protection techniques and its effects on temperature rise and voltage drop has also been discussed in this paper for the optimum design of superconducting solenoid from quench point of view.
