Abstract : The beam fluctuations propagating through the potential minimum and along the accelerating stream in crossed-field diodes of infinite cross section have been studied theoretically in four different analyses. Two analyses similar to the Llewellyn-Peterson diode treatment of a single-velocity stream were done. The spacecharge wave differential equation for such a stream was derived. A Monte Carlo numerical study was made on the digital computer for comparison with the approximate theories mentioned above and an approximate theory for the potential minimum. Good agreement was found among the theories at low frequencies and close quantitative agreement of these with a noise measurement was observed. (Author)
