| Popis: | The compression of the electron beam and the efficiency of the gyrotron are strongly dependent on the magnetic field. Especially for gyrotrons using pulsed magnets, the pulsed magnet provides a strong magnetic field to the gyrotron but also brings some new problems in magnet design and testing. In this article, we take the pulsed magnet design and test of an 800-GHz gyrotron as an example. Considering the needs of working at room temperature and withstanding severe electromagnetic forces, the treatment of magnet strength in design and fabrication is introduced in detail. The design and measurement of the magnetic field distribution are also presented. Finally, a pulsed magnet that can generate a 30-T magnetic field and can be repeatedly discharged is designed and experimentally verified. |
