Abstract

The authors present a procedure for the analysis of the operating margin of a pulsed magnet, based on the sequential calculation of magnetic field, AC losses, temperature, temperature margin, and energy margin. The procedure is suited to the analysis of supercritical helium, force-flow cooled magnets. An example of application to the ITER (International Thermonuclear Experimental Reactor) central solenoid and the diverter coils is given, showing the capabilities achieved by an integrated analysis code and the level of detail in the information gained
