Abstract

The invention relates to a medical linear accelerator deflection coil cleaning device for cleaning clogged impurities in accelerator deflection coils. The device comprises a water purification tank, awater pump, a water separator and a sewage tank which are arranged in sequence. The water purification tank is connected with a water inlet of the water separator through a first high pressure waterpipe, the water pump is arranged on the first high pressure water pipe, the water separator is a six-way water separator, each water outlet is provided with a pressure regulating valve, the water outlets of the water separator are connected with inlets of the accelerator deflection coils through second high pressure water pipes, and the sewage tank is connected with outlets of the accelerator deflection coils. Compared with the prior art, the medical linear accelerator deflection coil cleaning device has the advantages of long service life, low cost, wide range of use, time shortening, convenient installation and the like.

Description

technical field [0001] The invention relates to the field of cleaning a deflection coil of a medical linear accelerator, in particular to a cleaning device for a deflection coil of a medical linear accelerator. Background technique [0002] After the electrons are accelerated close to the speed of light, the Elekta medical linear accelerator needs to deflect and hit the target according to the design requirements to generate the required energy rays. The deflection yoke system consists of 3 pairs of coils, through which a large current flows, a magnetic field is generated, and the electrons are deflected. The coil current is large, and the heat generation is also large. The center of the coil winding is hollow, and the water flows through the center to take away the heat. The water flow of the coil winding flows through the inside, and the inner wall is oxidized to produce impurities, which are prone to blockage. [0003] In this case, one is to replace the coil, and the s...
