Logics of selection of the main parameters of the EMG helical coil

The paper describes one of the possible approaches to a selection of the main parameters of a multi-sectional helical coil of EMG in order to get the required level of the finite current. Each section of the EMG helical coil operates as an independent element with the given coefficient of current amplification. The rate of the coil turns inductance transfer is increased. The helical EMG is described, that can be used for experimental testing of the amplifying abilities of EMG and its separate sections in a "hot" mode. The paper describes the experimental results, gives the comparison and analysis of the calculations and experimental values of some parameters. The conclusions are made, that characterize the level of validity of the EMG multi-sectional helical coil main parameters selection.

Introduction

High-power current pulses are necessary to perform physical experiments. There are different types of pulsed power sources, and among them the capacitor type facilities and the explosive magnetic generators (EMG) are most widely practised.
