Flat-Top Magnetic Field Facility for Pulse Terahertz Gyrotrons

Pulse gyrotrons have lingered at the short-pulse operation below 1 ms because of the rapid changes in magnetic field strength. This article is aiming to incorporate the Flat-Top Pulse Magnetic Field (FTPMF) into the pulse-magnet gyrotron, which means there will be the first chance to make a pulse-magnet gyrotron available to generate radiation up to 10 ms or above. In such a long pulse width, many scientific experiments, Namely, ESR or DNP-NMR, can be carried out. This article will propose a suitable FTPMF facility for pulse gyrotrons. The topology, principle, and simulation result will be given.
