Description

technical field [0001] The invention belongs to the technical field of cyclotron magnetic field measurement, in particular to a compact cyclotron magnetic field measurement system sensor radial movement device. Background technique [0002] Cyclotrons are widely used in the field of nuclear medicine, especially in the fields of radiopharmaceuticals and tumor treatment. Hefei Ion Medicine Center has done a lot of research and experimental work on the development of a compact superconducting cyclotron. The host system of the superconducting cyclotron is used to extract a stable beam, and the electromagnetic field of the resonant cavity accelerates the beam, and the movement of the beam needs to be constrained by an isochronous magnetic field. In order to ensure the provision of an isochronous magnetic field, it is necessary to measure the magnetic field of the cyclotron. The magnetic field is a very important part of the cyclotron. The magnetic field provides a constraint fo...
