Physics-based Model for Nonuniform Thermionic Electron Emission from Polycrystalline Cathodes
Dongzheng Chen, Ryan Jacobs, John Petillo +4
Experimental observations of thermionic electron emission demonstrate a smooth transition between TL and FSCL regions of the emitted-current-density-versus-temperature (J-T) (Miram…
Quantum efficiency enhancement of bialkali photocathodes by an atomically thin layer on substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +15
We report quantum efficiency (QE) enhancements in accelerator technology relevant antimonide photocathodes (K2CsSb) by interfacing them with atomically thin two-dimensional (2D) cr…
Free-standing bialkali photocathodes using atomically thin substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
We report successful deposition of high quantum efficiency (QE) bialkali antimonide K2CsSb photocathodes on graphene films. The results pave a pathway towards an ultimate goal of e…
Heating of Micro-protrusions in Accelerating Structures
A. C. Keser, T. M. Antonsen, G. S. Nusinovich +2
The thermal and field emission of electrons from protrusions on metal surfaces is a possible limiting factor on the performance and operation of high-gradient room temperature acce…
Space Charge Effects in Field Emission: One Dimensional Theory
Alex Rokhlenko, Kevin Jensen, Joel L. Lebowitz
The current associated with field emission is greatly dependent on the electric field at the emitting electrode. This field is a combination of the electric field in vacuum and the…
Quantum Entangled Supercorrelated States in the Jaynes-Cummings Model
A. K. Rajagopal, K. L Jensen, F. W. Cummings
The regions of independent quantum states, maximally classically correlated states, and purely quantum entangled (supercorrelated) states described in a recent formulation of quant…
