“…R fuse is obtained using the a model developed in house and the time variation of the accelerator self-inductance is obtained from the 2D magnetic field distribution produced by a parallel transmission line with a homogeneously distributed current flowing through both the flyer and the stator plates. Full details of the calculation are presented elsewhere [1]. Theoretical predictions obtained using the model were compared with the experimental data for which the main AMPERE system parameters are: capacitance 129 μF, initial charging voltage 21.5 kV, bank resistance 8.8 m and bank self-inductance 650 nH.…”

“…The results are providing a series of important data: the complete map of magnetic and electric fields, current, force and temperature distributions, the accelerating time-dependent flyer position, etc. Full details of the implementation of this model are provided elsewhere [1]. In the example below, the flyer and the stator are each represented by a total collection of 400 filaments, with 200 independent currents.…”

A common initiative for the research into the physics and technology of a flyer plate electromagnetic accelerator has been started at AWE, Aldermaston and Loughborough University. Two electromagnetic accelerators have been constructed and tested: AMPERE, a 120 kJ / 40 kV capacitor bank system at AWE and QUATTRO a 100 kJ/30 kV capacitor bank system at Loughborough Pulsed Power Laboratory. Two numerical models for simulating the foil-flyer accelerator have been developed: a 0-D anda 2-D. The 0-D model is providing a useful tool for designing and for parametric studies and the 2-D model for accurately calculating all the details of the accelerator such as: the velocity, acceleration and temperature of the flyer the current distribution and the overall distribution of the magnetic and electric fields generated during a shot. The paper will present the most relevant experimental data obtained during the first phase of the joint programme and compare it with theoretical predictions.
