Noise Phenomena in Crossed-Field Electron Beams.

Noise Studies on Injected-Beam Crossed-Field Devices.

“…Some recent theoretical work by several investigators, supported by the Air Force, in fact shows that the potential minimum due to space-charge tends to smooth the noise. The results of these investigations has been summarized by Kooyers and Shaw of UCA Systems, and is reproduced here as Table IV 13 . What is clear is that present theory is still inadequate to give a quantitative explanation of the phenomena observed.…”
