An eccentric particle collection device with magnetic field rotation

Abstract

The invention discloses an eccentric particle collection device with magnetic field rotation. A horizontal magnetic field is applied through two magnetic blocks, so that the particles injected at the particle injection end below are rotated under the action of the magnetic field, and the rotation plane is perpendicular to the direction of the magnetic field. At the same time, the particles The radius of rotation is proportional to the energy of the particles; at the horizontal position on one side of the rotation direction, a plurality of particle collection blades that are close to the particle injection end are set in turn from high to low, and the particle collection blades collect particles with gradually reduced energy from high to low. The present invention uses eccentric multi-stage collector blades to collect particles, and the injected particles rotate under the action of the magnetic field and deviate from the incident hole at the particle injection end. Due to the effect of the magnetic field, the rotation radius is also greatly reduced due to the rotation reflection, and most of the secondary particles will not return to the position of the incident hole, thereby reducing the backflow rate and improving the particle collection efficiency.

Description

technical field [0001] The invention belongs to the technical field of particle collection, and more specifically relates to traveling wave tubes, back wave tubes, klystrons, gyrotrons, free electron lasers, Oro tubes, terahertz maser vacuum electronic devices, and particle linear accelerators Particle collection devices used in vacuum particle devices such as cyclotrons and synchrotron radiation machines Background technique [0002] A particle collection device that must be used in most vacuum devices, including traveling wave tubes, return wave tubes, and linear accelerators. The main function of the particle collection device is to collect the particles that have completed the interaction, that is, to recover the remaining energy, reduce particle radiation and backflow, and enhance heat dissipation. Multistage step-down collectors are often used when the collector and overall device efficiency need to be improved. [0003] Most of the existing particle collection devic...
