Abstract
The invention is directed to a ranging gun (1a to 1f) for a mass (17, 18) which is to be accelerated. The ranging gun comprises a coaxial system as acceleration system, which coaxial system consists of an outer conductor (2) and an inner conductor (3) which are electrically connected with one another by means of a short-circuit bridge (9) which terminates the coaxial system. In the coaxial system, a strong current pulse is fed at one side. Next, an explosive charge, which is aligned along the coaxial system, is ignited at the feed location so that the outer and inner conductors (2, 3) contact and a closed hollow space (10) is formed. The front termination is formed by a plasma bridge (11) which has formed from the short-circuit bridge (9) by means of the vaporization of the bridge material after feeding the strong current pulse. The magnetic field enclosed in the hollow space (10) is compressed by means of the forward moving detonation front, wherein, by means of adapting the mass of the plasma bridge (11 ), the dimensioning of the hollow space (10) can be adjusted along the entire compression distance in such a way that magnetic field compression occurs.
