MULTISLOT MAGNETRON Russian patent published in 2008 - IPC H01J25/58 

FIELD: electrical engineering.

SUBSTANCE: multislot magnetron has dimensions of anode and cathode along direction of constant magnetic field that exceed length of wave in free space. Anode design includes periodic system of disks made of soft magnetic material. Profile of their cross section fully follows profile of resonators, to which constant magnets are connected with radial or axial magnetization, polarity of which on neighboring disks is changed for the opposite one. Rings made of soft magnetic material are introduced into cathode design, and they are installed symmetrically in relation to transverse planes that pass through the middle of every of above mentioned disks.

EFFECT: improvement of weight and size characteristics.
