Abstract:
One of the tools for the formation of preheated magnetized plasma, necessary for the fusion ignition, are pulsed plasma accelerators, which have gone an impressive development path from the Marshall gun to accelerators of compact tori and plasma toroids. By colliding plasma flows and optimizing their parameters, it is possible not only to create a pulsed fusion device with a positive energy output, but also to efficiently convert their kinetic energy into the energy of linear EUF and X-ray radiation, which can lead to the development of equipment for promising technological applications and short-wave coherent directional radiation generators. The purpose of this work is to develop a simplified model and calculate the neutron yield during free passage through each other of both deuterium plasma flows and deuterium and tritium plasma flows. Based on the calculation results, the minimum values of the energy content and velocity of plasma flows are estimated, which must be provided in order to obtain the maximal values of the neutron yield. In this work, the calculations do not take into account the loss of kinetic energy of deuterons and tritons for heating the electronic component of the plasma.
