The invention relates to the field of measuring magnetic quantities. A method for measuring a magnetic field in the median plane of a cyclotron comprises steps of: using a controller to form an algorithm for moving a bar, which is equipped with additional Hall sensors. In accordance with a given algorithm, the bar is moved by a given step in the radial and azimuthal direction around a full circle, and then the same movements are repeated but in the opposite direction. The bar is stopped at fixed positions, in accordance with the given algorithm, for a fixed time to measure the current from the Hall sensors. An individual map of measurement point coordinates is formed such that in areas of high magnetic field strength gradient, the density of measurement points is higher. The magnetic field of the cyclotron is measured according to the individual map of measurement point coordinates. The technical result is simplifying the procedure and reducing the measurement time of the cyclotron magnetic field.
This method for measuring magnetic quantities relates to the field of measuring magnetic quantities, and more specifically, to a system for measuring the magnetic field in the median plane of an isochronous superconducting cyclotron.
A cyclotron is an accelerator that uses a magnetic field to impart cyclotron motion to charged particles, and the beam is repeatedly accelerated by a high-frequency electric field. An isochronous magnetic field must be generated in a cyclotron, so magnetic field induction measurements are performed across the entire pole surface range. An isochronous superconducting cyclotron is the core equipment of a proton therapy system. An isochronous magnetic field is crucial for producing a high-quality particle beam with a specific energy and intensity. The magnetic system is the most important component of a cyclotron. The magnetic field provides the focusing force for beam motion.
