Title: Helix progressive waveguide
Inventor: SATOU HISAAKI
IPC: H01J23/087
Filed: 1979-12-19
Abstract: PURPOSE:To allow stable operation even in high power level in such a way that a cooling fin is installed over the outside of a magnet at one part on the output side of a high frequency circuit part, and draft passage partition plates are installed for specially increasing the flow speed of cooling draft in the vicinity of the cooling fin. CONSTITUTION:Draft passage partition plates 15, 15' to make draft current  narrower are installed in the vicinity of a cooling fin 14 in the high frequency circuit. This facilitates to increase the speed of cooling draft to pass through the cooling fin 14, and to improve cooling effects. Besides, since the partition plates 15, 15'  are installed only between relatively shorter area in the guide axial direction, the  total static pressure is not so much increased.
