Description

Technical field [0001] The invention belongs to the technical field of superconducting cyclotrons, and specifically relates to a magnetic field measuring device and a measuring method for the first harmonic of a superconducting coil. Background technique [0002] Cyclotron is a device that uses magnetic field and electric field to make charged particles in cyclotron motion and is repeatedly accelerated by high-frequency electric field in motion. It is an important instrument in high energy physics. Superconducting cyclotron is the core equipment of medical proton therapy accelerator. The medical proton therapy accelerator can treat tumors with proton and heavy ion radiation in the microcosm. It is the most cutting-edge radiotherapy technology in the world today. Only a few developed countries have mastered and applied this technology. The development of the superconducting cyclotron has been launched in China but has not yet been completed. [0003] The superconducting cyclotron m...
