H01J25/36 - CPC Classification

Classification description:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons; Travelling-wave tubes; Tubes in which a travelling wave is simulated at spaced gaps Tubes in which an electron stream interacts with a wave travelling along a delay line or equivalent sequence of impedance elements, and without magnet system producing an H-field crossing the E-field

Sub-classes:

H01J25/38 » the forward travelling wave being utilised 6
H01J25/40 » the backward travelling wave being utilised 3
