Problems solved by technology

[0003] The long-distance transmission of the relativistic electron beam has very high requirements for the collimation method of the electron beam. However, in the process of realizing the present invention, the inventors have found that common collimation methods such as magnetic quadrupole lenses and external magnetic fields are used in long-distance transmission. In this scenario, its cost and complexity have increased exponentially, engineering application is more difficult, and there are technical problems that cannot effectively carry out long-distance stable transmission

Abstract

The invention relates to a relativistic electron beam transmission scheme design method and device, equipment and a medium. The method comprises the following steps: calling a background plasma environment space model; injecting the relativistic electron beam into a plasma channel by adopting an external injection method, and performing long-distance constraint on the relativistic electron beam by utilizing an excited tail wave field transverse field; adjusting transmission parameters of the relativistic electron beam, and performing transmission simulation; according to set boundary conditions, adopting a high-order particle cloud interpolation method to solve the current, adopting a fourth-order finite difference method to solve the Maxwell equation, and obtaining a simulation result of the relativistic electron beam after parameter adjustment through calculation; and determining an optimal simulation result according to the simulation result, and outputting a transmission parameter corresponding to the optimal simulation result as a relativistic electron beam transmission scheme design result, wherein the optimal simulation result is the simulation result when the beam spot of the relativistic electron beam is minimum, the energy collimation is optimal and the energy loss is minimum. The effect of efficient long-range stable transmission of relativistic electron beams is achieved.
