Continuous-Wave Operation at 30 MV/m of a Superconducting Radio-Frequency Gun Cryomodule with an Exchangeable Cathode Plug

T. Konomi, T. Xu, Y. Choi +30

A prototype 185.7 MHz superconducting radio-frequency (SRF) electron gun cryomodule has been developed for the proposed LCLS-II-HE Low Emittance Injector at SLAC. It has an in-situ…

The construction and characterization of MgO transmission dynodes

H. W. Chan, V. Prodanović, A. M. M. G. Theulings +5

In this work we demonstrate that ultra-thin (5 and 15 nm) MgO transmission dynodes (tynodes) with sufficient high transmission electron yield (TEY) can be constructed. These tynode…

The Future of Gamma-Ray Experiments in the MeV-EeV Range

Kristi Engel, Jordan Goodman, Petra Huentemeyer +95

Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about par…

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…

Near atomically smooth alkali antimonide photocathode thin films

Jun Feng, Siddharth Karkare, James Nasiatka +3

Nano-roughness limits the emittance of electron beams that can be generated by high efficiency photocathodes, such as the thermally reacted alkali antimonide thin films. However th…

Optical properties of silicon rich silicon nitride (SixNyHz) from first principles

Shu Xia Tao, Anne M. M. G. Theulings, Violeta Prodanović +2

The real and imaginary parts of the complex refractive index of SixNyHz have been calculated using density functional perturbation theory. Optical spectra for reflectivity, adsorpt…
