Protecting Aerospace Devices via an Ion-Material Interaction Benchmark

October 22, 2018

In outer space and other harsh radiation environments, high-energy ions and protons pierce materials and affect nearby electronic systems. Known as a single-event effect (SEE), the particle radiation can lead to soft or hard errors in devices. Since just one hard error puts a space mission at risk, aerospace engineers must make sure that all critical electronic devices can withstand an SEE. To gain a better understanding of this phenomenon, they can accurately analyze the ion-material interaction using simulation.

Sampling from Phase Space Distributions in 3D Charged Particle Beams

September 22, 2016

In the previous installment of this series, we explained two concepts needed to model the release and propagation of real-world charged particle beams. We first introduced probability distribution functions in a purely mathematical sense and then discussed a specific type of distribution — the transverse phase space distribution of a charged particle beam in 2D. Now, let’s combine what we’ve learned and find out how to sample the initial positions and velocities of 3D beam particles from this distribution.

Phase Space Distributions and Emittance in 2D Charged Particle Beams

September 19, 2016

Previously in our Phase Space Distributions in Beam Physics series, we introduced probability distribution functions (PDFs) and various ways to sample from them in the COMSOL Multiphysics® software. Such knowledge of PDFs is necessary to understand how ion and electron beams propagate within real-world systems. In this installment, we’ll discuss the concepts of phase space and emittance as they apply to the release of ions or electrons in beams.

Sampling Random Numbers from Probability Distribution Functions

September 15, 2016

In this blog series, we’ll investigate the simulation of beams of ions or electrons using particle tracking techniques. We’ll begin by providing some background information on probability distribution functions and the different ways in which you can sample random numbers from them in the COMSOL Multiphysics® software. In later installments, we’ll show how this underlying mathematics can be used to accurately simulate the propagation of ion and electron beams in real-world systems.
