Quantitative evaluation of emission uniformity of the annular explosive emission cathode

Physics of Plasmas, 2022
Explosive emission cathodes (EECs) are widely used in the field requiring intense electron beams. The uniform emission of EECs is vital for applications. To effectively evaluate the emission uniformity of annular EECs, this paper proposes a quantitative evaluation model based on the analysis of cathode plasma images and constructs a parameter which is ...

Emission uniformity and emission area of explosive field emission cathodes

Applied Physics Letters, 2001
Explosive field emission cathodes have been used extensively in high power microwave tubes. These cathodes emit electrons without the use of cathode heaters. Recently, some theoretical and simulation work has been performed to gain further understanding of the physics of these cathodes.

Emission uniformity and emittance of explosive field-emission cathodes

IEEE Transactions on Plasma Science, 2002
Explosive field-emission cathodes as well as plasma-flashover cathodes are important for high-power microwave tubes. These cathodes have the advantage of being lightweight as well as requiring no heater for electron emission. However, this class typically suffers from large amounts of outgassing, nonuniform emission, and very high emittance.

CNT electron source with uniform emission distribution

Fifth IEEE International Vacuum Electronics Conference (IEEE Cat. No.04EX786), 2004
The carbon nanotube (CNT) has been well known as a good field emission material by its superior structure, such as small radius and high aspect ratio. It has also been said that a large sized cathode plate can be easily fabricated at low cost by a CNT paste printing technique. However, the CNT has a cohesive characteristic in its nature and the printed

Coherent fluorescent emission and scattering from a uniform sphere

Physical Review A, 1991
The coherent light inelastically scattered from an ideal fluorescent sphere illuminated by an electromagnetic wave is analyzed using an extension of Mie theory. Scattering coefficients are solved specifically for plane-wave illumination. The resulting inelastically scattered radiation is similar to that of elastically scattered radiation from a sphere.

Uniform emission taxes, abatement, and spatial disparities

Australian Journal of Agricultural and Resource Economics, 2020
This paper examines how a commitment to a common tax on greenhouse gas (GHG) emissions affects spatial distribution of production and welfare between countries. To focus on the long‐term effects of firm relocation, the paper employs a two‐country model of monopolistic competition with a variable abatement technology.

Emission uniformity studies of gyrotron MIG cathodes

Third IEEE International Vacuum Electronics Conference (IEEE Cat. No.02EX524), 2003
Recent studies indicate that unwanted mode competition is often generated in a gyrotron due to nonuniform emission of electrons from the thermionic cathode used in MIG electron guns. This mode competition significantly decreases the microwave efficiency of the device.
