The minimum noise figure of a 1ongitudinal-beam amplifier utilizing velocity modulation is limited by the uncorrelated noise power in the slow space-charge waves [1] (p.148) because these are the active modes of a beam; that is, they have the properties of negative resistances. Beam noisiness constitutes the main contribution to the noise output of a similar
