Abstract: 

The simulation results of multi-segment permanent magnet magnetic focusing system for clinotrons in submillimeter range have been presented. The visualization of magnetic field distribution in the gap between the system magnetic poles was done with the help of computer simulations. The simulation results are compared with those obtained experimentally. The magnetic field distribution curves of both single segment and whole multi-segment magnetic system are presented. It is shown that for a given configuration of the magnets in the system gap of 32 mm the magnetic field of 1.1 T is obtained. The generation parameters of clinotrons with developed magnetic focusing system were experimentally obtained in submillimeter range.
