Fast Pattern Recognition for Electron Emission Micrograph Analysis
Taha Y. Posos, Oksana Chubenko, Sergey V. Baryshev
In this work, a pattern recognition algorithm was developed to process and analyze electron emission micrographs. Various examples of dc and rf emission are given that demonstrate…
Evidence for Anti-Dowell-Schmerge Process in Photoemission from Diamond
Tanvi Nikhar, Sergey V. Baryshev, Gowri Adhikari +1
A great number of metal and semiconductor photocathodes, which are of high practical importance for photoinjector applications, closely follow the 1/3 gradient Dowell-Schmerge (DS)…
FEgen (v.1): Field Emission Distribution Generator Freeware Based on Fowler-Nordheim Equation
Emily Jevarjian, Mitchell Schneider, Sergey V. Baryshev
FEgen is a comprehensive user interface designed to create initial particle distributions for field emission sources operated in rf guns (additional capability exists for dc pulsed…
Demonstration of Planar Ultrananocrystalline Diamond Field Emission Source Operating in SRF Injector at 2 Kelvin
Sergey V. Baryshev, Erdong Wang, Chunguang Jing +9
Reported here is the first demonstration of electron beam generation in an SRF TESLA 1.3 GHz gun equipped with field emission cathode when operated at 2 Kelvin. The cathode is subm…
Field emission microscopy of carbon nanotube fibers: evaluating and interpreting spatial emission
Taha Y. Posos, Steven B. Fairchild, Jeongho Park +1
In this work, we quantify field emission properties of cathodes made from carbon nanotube (CNT) fibers. The cathodes were arranged in different configurations to determine the effe…
Revisiting Effects of Nitrogen Incorporation and Graphitization on Conductivity of Ultra-nano-crystalline Diamond Films
Tanvi Nikhar, Robert Rechenberg, Michael Becker +1
Detailed structural and electrical properties of ultra-nano-crystalline diamond (UNCD) films grown in H/CH/N plasma were systematically studied as…
