First Operation of an Ungated Diamond Field-Emission Array Cathode in a L-Band Radiofrequency Electron Source
P. Piot, C. A. Brau, B. K. Choi +9
We report on the first successful operation of a field-emitter-array cathode in a conventional L-band radio-frequency electron source. The cathode consisted of an array of $\sim 10…
A probability-conserving cross-section biasing mechanism for variance reduction in Monte Carlo particle transport calculations
Marcus H. Mendenhall, Robert A. Weller
In Monte Carlo particle transport codes, it is often important to adjust reaction cross sections to reduce the variance of calculations of relatively rare events, in a technique kn…
Fast Computation of Voigt Functions via Fourier Transforms
Marcus H. Mendenhall
This work presents a method of computing Voigt functions and their derivatives, to high accuracy, on a uniform grid. It is based on an adaptation of Fourier-transform based convolu…
A Fast, Vectorizable Algorithm for Producing Single-Precision Sine-Cosine Pairs
Marcus H. Mendenhall
This paper presents an algorithm for computing Sine-Cosine pairs to modest accuracy, but in a manner which contains no conditional tests or branching, making it highly amenable to…
An Algorithm for Computing Screened Coulomb Scattering in Geant4
Marcus H. Mendenhall, Robert A. Weller
An algorithm has been developed for the Geant4 Monte-Carlo package for the efficient computation of screened Coulomb interatomic scattering. It explicitly integrates the classical…
