Highexplosivedriven delay line pulse generator
Abstract
The inclusion of a delay line circuit into the design of a highexplosivedriven generator shortens the time constant of the output pulse. After a brief review of generator concepts and pulseshortening methods, a geometry is presented which incorporates delay line circuit techniques into a coil generator. The circuit constants are adjusted to match the velocity of the generated electromagnetic wave to the detonation velocity of the high explosive. The proposed generator can be modeled by adding a variable inductance term to the telegrapher's equation. A particular solution of this equation is useful for exploring the operational parameters of the generator. The duration of the electromagnetic pulse equals the radial expansion time of the high explosive driven armature until it strikes the coil. Because the impedance of the generator is a constant, the current multiplication factor is limited only by nonlinear effects such as voltage breakdown, diffusion, and compression at high energies.
