Cavity tunable resonant with compensation of altitude, in particular for a device for the emission of electrons has fields crusaders embarked on board a 371

摘要

P to the invention relates to tubes micro -. & / p & & p & the structure of the tuning 16 of a magnetron has agility of the tuning frequency has a plunger 28 coupled by a first gusset 24 has a matching end of a rod 32. The end opposite of the rod of the tuning is coupled by a second bellows 48 has an enclosure at vacuum of compensation 42. When the two bellows are identical, the forces atmospheric which act on the upper chord are balanced at any altitude. / p & & p & application to the radar. / p
