Abstract

Al though much progress has been made in the understanding of the high-frequency noise behaviour of electron streams [1], many problems remain, especially in the correlation of theory with experiment in the low-velocity region. Perhaps the major difficulty results from the fact that most experiments must be made in the high-velocity region through the determination of induced noise current, noise figure, or correlation coefficients in the accelerated beam. Deductions may then be made concerning conditions in the low-velocity region, but often the deductions are not unique.
