FIELD: UHF equipment engineering. ^ SUBSTANCE: lamellas of anode are made so that in projection of cross-section of device on the side of north pole of magnetic system relation l>p is upheld, where l - distance between axis of device and line of intersection of lamella surface, facing the cathode, and left side surface of lamella, p - distance between axis of device and line of intersection of surface of lamella, facing the cathode, and right side surface of lamella. Also, surface of lamella, facing the cathode, may consist of two sides, parallel to axis of device and positioned relatively to one another at an angle lesser than 180°. ^ EFFECT: increased lifetime. ^ 2 cl, 5 dwg |
