Cathode-Ray Bunching [PDF]

open access: bronzeJournal of Applied Physics, 1939
The bunching of cathode rays in the klystron, described in this Journal by R. H. Varian and S. F. Varian, is treated mathematically here, and is found to result in a current having a wave form with sharp peaks and containing strong higher harmonics.

The Cathode Ray Oscillegraph in Industry [PDF]

open access: bronzeNature, 1946
APPLICATIONS of the sealed-off cathode-ray XX tube to the field of radio have been previously well treated, so the author gains by concentrating on other applications, which are shown to be wide and valuable. Controlling electron beams in'cathode-ray tubes, electron diffraction tubes, and electron micro scopes exhibits many common features, and the ...

The scattering of cathode rays [PDF]

open access: goldProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1926
Scattering experiments with a view to investigating the dynamical laws governing the encounter of a fast electron with an atomic nucleus have hitherto been made with the β-rays from radioactive substances. These measurements have had to be made under circumstances of peculiar experimental difficulty, owing to the small intensity available in a beam of ...

Scalable Precursor-Assisted Synthesis of a High Voltage LiNiyCo1−yPO4 Cathode for Li-Ion Batteries

open access: yesNanomaterials, 2023
A solid-solution cathode of LiCoPO4-LiNiPO4 was investigated as a potential candidate for use with the Li4Ti5O12 (LTO) anode in Li-ion batteries. A pre-synthesized nickel–cobalt hydroxide precursor is mixed with lithium and phosphate sources by wet ball ...
