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...
