Description

technical field

[0001] The invention mainly relates to a high-voltage accelerating tube, in particular to a high-voltage accelerating tube for accelerating electrons, ions, protons, carbon particles and other particles. Background technique

[0002] The accelerator tube is a channel that can accelerate charged particles uniformly under a certain voltage. It is composed of a lot of insulating connecting rings and a piece of metal accelerating electrode. Each accelerating electrode of the accelerating tube is connected with the voltage equalizing ring, so that the voltage drop between the charged electrode gaps on the entire length of the accelerating tube is equalized, and the pressure resistance of the accelerating tube is improved. In order to make the charged particles be uniformly accelerated when they pass through each electrode, and keep the beam from spreading, the metal accelerating electrode sheet is not only made into a circular flat...
