Simulation optimization on quench analysis of wide aperture superconducting quadrupole magnet

Wide aperture superconducting magnets are used in different accelerator laboratories as spectrometer magnets. These magnets are used in the accelerator facilities like ANURIB project, Kolkata, newly constructed BIGRips facility in Japan and FAIR project in GSI, Germany. Quench simulation is an important part of the design of superconducting magnet. The present simulation has been carried out using QUENCH code and QUENCH-ELECTRA coupled code of Vector Fields software for wide aperture superconducting quadrupole magnet. Since the quench calculation is highly nonlinear in nature, Computation time is generally high. As increased computation time increases cost of design, choosing proper mesh size and time stepping tolerances play an important role during quench calculation. This paper will discuss about convergence of hot spot temperature and maximum voltage on mesh size, tolerance criteria. Computation time for each case, effect of delay in actuation of quench circuit will also be discussed.
