Abstract

The invention discloses a device and method for coaxially assembling a gyrotron body and a magnet. The method comprises: a driving coil is wound around the gyrotron body inside a gyrotron magnet; whenthe driving coil is energized, the electromagnetic force of a magnetic field inside the gyrotron magnet acts on the driving coil, and the current direction of the driving coil is opposite to the current direction of the gyrotron magnet, and the magnetic field distribution inside the gyrotron magnet is configured such that from the magnetic axis of the gyrotron magnet to the inner wall of the magnet, the intensity of the magnetic field gradually increases; according to the left-hand rule of an energized coil in the magnetic field, the resultant force of the electromagnetic force acting on thedriving coil is directed to the magnetic axis direction, so as to drive the gyrotron body to move toward the magnetic axis direction, so that the axis of the gyrotron body coincides with the magneticaxis of the gyrotron magnet. The method enables the gyrotron body to perform a damping motion under the driving of the electromagnetic force acting on the driving coil, and finally makes the axis of the gyrotron body and the magnetic axis of the gyrotron magnet substantially coaxial with each other.

Description

technical field [0001] The invention relates to the field of magnetic field technology, and more specifically, to a coaxial assembly device and method for a gyrotron body and a magnet. Background technique [0002] Gyrotrons are currently the main high-power millimeter-wave and submillimeter-wave sources, so they are widely used in plasma heating, electron spin resonance spectroscopy, material processing, terahertz imaging, radar communication and other fields. A gyrotron is a fast-wave device based on an electron gyrotron maser. The electron cyclotron maser is based on the relativistic effect. The electrons emitted by the electron gun form a hollow electron beam with a certain cyclotron frequency under the adiabatic compression of the magnetic field. A phenomenon in which energy is delivered to electromagnetic waves to produce electromagnetic radiation. Among them, the coaxial installation of the axis of the gyrotron body and the magnetic axis of the gyrotron magnet is pa...
