.~.~ Traveling wave type
DEFINITION
Classification: 331/82
(under subclass 81) Subject matter wherein the means controlling the beam comprises a transmission line of the slow wave type placed in energy exchanging relation to the beam of particles, the axes of the transmission line and the beam being in the same general direction, the transmission line being so constructed that the phase velocity of a component of a traveling electromagnetic wave propagated therealong approximates the velocity of the beam of particles being such that the wave gains in energy while the particles lose energy, the slowing down of the particles causing groups or bunches to form.
