Radiated fields in rail launchers operation

In this paper electromagnetic fields radiated from a railgun operating syst em with a plasma armature are investigated. A small-bore railgun has been f abricated in our laboratory, a capacitor bank (0.12 F-160 V) has been used as energy supply and an experimental setup has been implemented, Experiment s have been performed in a remotely operated shielded semi-anechoic chamber in conformity with current standards. The analysis has been conducted in t he time domain, using suitable current probes and antennas and an oscillosc ope with high bandwidth and high sampling rate. Results were reproducible a nd a comparison and discussion with previous work are reported.
