Friedwardt Winterberg has an improved method for generating impact nuclear fusion

Friedwardt Winterberg has an improvement on a method to generate the ultrafast jets that are needed for impact nuclear fusion.

It is shown that in contrast to the electric pulse power driven implosion of a single conical wire array, the implosion of a nested conical wire array with opposite alternate opening angles can lead to the generation of fast jets, with velocities of the order 10^8 cm/s. This technique can be applied for the supersonic shear flow stabilization of a dense z-pinch, but possibly also for the fast ignition of a pre-compressed dense deuterium-tritium target.



Back in 1967, Winterberg had proposed to reach very large jet velocities by the impact under a small angle of a projectile on a stationary solid target. For impact velocities of ~10^7 cm/s and an angle of less than 10 degrees, jet velocities of the order 10^8 cm/s could be expected, as they are needed for impact fusion. Projectile velocities of ~10^7 cm/s can in principle be reached by the acceleration of a small superconducting solenoid with a magnetic travelling wave accelerator, but the length of such an accelerator was estimated to be of the order 10 km. However, it has been shown that such velocities can also be reached over a distance of a few cm by the electric pulse power driven implosion of a cylindrical thin wire array. This raises the question if with this technique jet velocities of the order 108 cm/s can be reached by the implosion of a conical wire array with a small opening angle. It turns out that this is not possible, but possible with a nested conical wire array.
