International audienceThis paper describes a new numerical method which analyzes adiabatic quench of superconducting coils.The method is a generalization of the Wilson's older method. With this new method the resistive front is not restricted to be an ellipsoid and can evolve with an arbitrary velocity at its border. The evolution of the resistive front is efficiently controlled by the introduction of the level-set method. The two-dimensional version presented here leads to a fast simulation code of the quench proces

The aim of this work is to prove the feasibility of providing high current pulses through the use of a superconducting pulsed power transformer. This article presents the design and tests of a 500 J pulsed power transformer. This paper also describes the computer code created to simulate the primary quench development. During the tests, the primary winding was charged to its rated current (500 A). The secondary being connected to a 0.7 mC2 and 0.2 pH load, we obtained through this load a pulsed discharge of 7.2 ms duration. The current rose to 12.3 kA in 0.5 ms and 38 YO of the energy stored in the primary winding was transferred to the load. This current and energy transfer between primary and secondary is the best one ever recorded for such a device.
