Electronic accelerator

Abstract

An electron accelerator includes a steel cylinder, a plurality of semicircular corona rings equipped inside the steel cylinder, a high voltage electrode equipped above the corona rings, two high frequency electrodes equipped outside the corona rings and the high voltage electrode, an electron gun, a vacuum accelerating tube equipped below the electron gun, a control system equipped outside the steel cylinder, a high frequency oscillator used to provide the electron accelerator with power and equipped outside the steel tube; a feedback capacitance plate equipped between the steel cylinder and the high frequency electrodes. The semicircular corona rings adopts opposite opening mode for arrangement symmetrically along the direction of the steel cylinder shaft axis. A feedback capacitance used to form high frequency oscillator electron tube triple-stage bias voltage is between the feedback capacitance plate and part of the high frequency electrodes. A compensation capacitance plate is equipped between the high frequency electrodes and the steel cylinder and can improve high frequency characteristic parameters. On the premise of no change for the distance among the high frequency electrons, the electron accelerator working frequency can be reduced and reach physical design requirements.

AI Technical Summary

Problems solved by technology

[0006] In the existing technology, the electron acceleration can be designed as a structure with a larger diameter at the top and a smaller diameter at the bottom. Such a structure will reduce the distance between the high-frequency electrode and the corona ring, which can increase the capacitance and reduce the frequency. Small, but because the radius of the steel cylinder at the lower part of the electron accelerator is reduced, the distance between the two high-frequency electrodes is reduced, so it cannot meet the requirements of strong current
