Abstract:

Laser guided, electric discharges in the atmosphere have been used to create 1m long, air plasma channels and have enabled experiments to study channel cooling and the interaction of intense relativistic electron beams REB with channels in the atmosphere. These discharges require driving potentials 100kV to follow the laser designated path, but only modest stored energy typically 1000J and -250kV were used. Some applications used two stage discharges wherein a second, lower voltage capacitor bank was discharged into the air plasma channel. The secondary discharges were tailored for each application which included channel resistance measurements the generation of an RF plasma antenna simulation of nuclear explosion induced lightning NEIL and studies of relativistic electron beam propagation in current carrying channels. We describe the different systems used to effect these discharges and consider the design of a system necessary to extend the discharge length to 10m.
