Cathode Sputtering in Hollow Cathode Discharges
Journal of the Physical Society of Japan, 1962In order to investigate the processes responsible for a negative resistance of the hollow cathode discharge, several discharge parameters are measured with a Langmuir probe. The vapor density distributions of the sputtered cathode metal are measured by the absorption method of the resonance radiation of the metal atom. Almost all the metal atoms in the

Modeling on plasma energy balance and transfer in a hollow cathode
Journal of Physics D: Applied Physics, 2019The hollow cathode lifetime is largely determined by the dissipation of the active emitter material and the ion-induced sputtering erosion. These two critical factors are involved in the physical mechanisms of the internal energy balance and plasma ...

Advanced Functional Materials, 2020
Prussian blue and its analogues (PBAs) have been proposed as promising cathode materials for sodium‐ion batteries (SIBs) due to high theoretical capacity and low cost, but they often suffer from poor electronic conductivity and structural instability ...

Low current heaterless hollow cathode neutralizer for plasma propulsion-Development overview.
Review of Scientific Instruments, 2019Hollow cathodes serve as electron sources for the operation of electric thrusters aboard spacecraft. Conventionally, hollow cathodes utilize a heating element to raise the temperature of the electron emitting material embedded in the cathode. To simplify

Heat and pressure characteristics in hollow cathode centered negative pressure arc column
Applied Thermal Engineering, 2019Arc characteristics are found greatly changed by the negative pressure from the hollow cathode. These changes affect the distribution of arc pressure, arc plasma flow and temperature along the arc column.

Tetragonal VO2 hollow nanospheres as robust cathode material for aqueous zinc ion batteries
, 2020The emerging aqueous zinc ion batteries (ZIBs) are one of the alternatives to lithium ion batteries (LIBs) because zinc electrode possesses low equilibrium potential, high exchange current density and high hydrogen evolution overpotential.
