Analysis of Multipacting using Field Scaled Particles in VSim

Diana M. Cheatham, Daniel Main, David N. Smithe, Seth Veitzer, Peter Stoltz, Jarrod Leddy, Ilya Zilberter, John R. Cary, "Analysis of Multipacting using Field Scaled Particles in VSim."  This presentation discusses field-scaled particles, which provide a method by which one can study multipacting at multiple values of the electromagnetic power in a single (non-self-consistent)simulation. Field-scaled particles are particles that can selectively respond to field strengths differently. Use of field-scaled particles requires that one have accurate surface fields, and appropriate secondary emission. To illustrate use of field-scaled particles, multipacting computations in both a coax and a spherical cavity are presented, showing that (1) correct surface fields are obtained, and (2) multipacting bands are visible in the simulation. These results are then compared with the more traditional simulation methods. This method is highly efficient and ideal for RF design optimization.

Tech-X Corporation Announces the Release of VSim 10

Simulate Field Emitter Arrays

Use VSim's radiation generation feature in design and manufacture of high power (terahertz) RF devices ranging from spectrometers to oscillators for applications in fields as diverse as biophysics and radio astronomy.  VSim for Microwave Devices accurately models particle beams with space charge, simple to complex field absorbers, and conformal dielectrics. Smith-Purcell radiation device simulation example included.

Full Wave Electromagnetics Plus Particle In Cell

VSim's Plasma Ionization feature can be used for simulating gas discharge tubes and gas phototubes.  Tech-X accurately models Plasma Ionization using Full Wave Electromagnetics plus Particle In Cell, with the most state-of-the-art reactions framework.  Townsend Discharge simulation example included.

Boulder, Colorado - July 25, 2018:
Tech-X will hold a VSim physics simulation software workshop in September at the 2018 International Conference on Electromagnetic Isotope Separators and Related Topics (EMIS XVIII) in Geneva, Switzerland from September 16-21.
Dr. Jonathan Smith from Tech-X will provide a brief introduction to the principles and algorithms behind particle in cell simulations. There will be a demonstration of the VSim software to kinetically model a low temperature/technological discharge plasma, and an opportunity to follow along on your own laptop and test problems of more interest to your own research. If you would like to follow along or try VSim yourself with a free temporary license and software download, please contact us.
