Abstract
A rail gun (10) comprising two elongate co-extensive rail electrodes (11,12) having confronting surfaces (17,18) which are of toothed cross-section configuration. The toothed configuration of the surfaces ensures that during the operation of the rail gun (10), there is not an electric current concentration in the vicinity of the confronting surfaces (17,18). Consequently problems associated with the overheating of the confronting surfaces (17,18) are reduced.
