Description

1. Technical field [0001] The invention relates to the technical field of manufacturing high-frequency and high-voltage electron accelerators. 2. Background technology [0002] In the prior art, the power supply device that provides high-frequency power for high-frequency and high-voltage electron irradiation accelerators is a power oscillation composed of a high-frequency flexible coaxial cable transmitted by a power oscillation tube and an inductance-capacitance resonant circuit in the main body of the accelerator. , and deliver high-frequency power to the accelerator capacitive load. High-frequency voltage doubler rectification, used as an accelerator to obtain megavolt-level acceleration voltage and kilowatt-level electron beam power for radiation processing. [0003] When the beam power is greater than 120KW, the flexible coaxial cable can no longer carry such a large high-frequency power, and the ultra-high-power hard coaxial electron beam is used instead. However, d...

Problems solved by technology

However, due to the disadvantages of high cost and difficult installation of hard coaxial electron beams, there are also problems of unstable operation of the power oscillator caused by parasitic parameters brought about by long-distance transmission, large loss of high-frequency transmission and high failure rate.
