Professor Cary, below, discussed Use of Computation for Understanding Plasmas in a video interview for the Michigan Institute for Plasma Science and Engineering Fundamentals of Plasmas Series.
In Use of Computation for Understanding Plasmas, part of The Fundamentals of Plasmas series of the Michigan Institute for Plasma Science and Engineering, Prof. John R. Cary explains how computer simulations are a form of virtual reality. Dr. Cary explains that by using computer simulations, you can solve the very complex equations that describe how plasmas form and interact with matter, and virtually sit inside the plasma. These computer simulations not only provide insights on the very basic plasma physics, but can also be used to design technology devices that use plasmas.
John Cary is CEO and co-founder of Tech-X Corporation, as well as Professor of Physics at the University of Colorado, Boulder. Dr. Cary received his PhD from the University of California, Berkeley. He previously worked at Los Alamos National Laboratory and the Institute for Fusion Studies at the University of Texas. Dr. Cary’s recent service to the physics community includes being associate editor for Reviews of Modern Physics, being on the Executive Committees of the Division of Plasma Physics and the Division of Beam Physics of the American Physical Society where he is currently chair of the Division of Plasma Physics. He has advised PhD and Masters degree students and taught at all university levels. A frequently invited speaker, Professor Cary’s interests are in computational physics, including algorithm development and modern approaches, beam physics, plasma physics, nonlinear dynamics, and electromagnetics of structures. Professor Cary is a fellow of the American Physical Society with over 170 refereed publications. John Cary has received awards including the Buneman Award for Visualization, the John Dawson Prize for Numerical Simulation of Plasmas, and the IEEE NPSS Charles K.

The Particle Accelerator Science and Technology Technical Committee (PAST) of the IEEE Nuclear and Plasma Sciences Society awards the prestigious Particle Accelerator Science and Technology Award to individuals who have made outstanding contributions to the development of particle accelerator science and technology. Two Awards are granted in each occurrence of the Particle Accelerator Conferences held in North America (NAPAC or IPAC): one award is given to a senior level scientist and technologist and the other award is given to an individual early in his/her career.
The 2019 PAST Awards will be presented at the 2019 North American Particle Accelerator Conference (NAPAC2019), which will be held in Lansing, Michigan USA, 1-6 September, 2019.
John R. Cary, is a Professor of Physics at the University of Colorado and a CEO of Tech-X Corporation who has made important and diverse contributions throughout accelerator science and related fields. Professor Cary’s contributions include basic discoveries in nonlinear dynamics and advances in computational physics, as well as their application to specific accelerator and beam systems. Much of his work (separatrix crossing, one of Arnold’s 10 mathematical discoveries of the 1980s, and electromagnetic algorithms) has been fundamental and cited in many other fields. His work on advanced accelerator physics includes the computational illustration of self-trapping and the acceleration of electrons from laser-plasma interaction (one of the Nature’s scientific highlights of 2004), determination of the reasons for the observed emittance difference along and transverse to the direction of the laser polarization, and the method for combining laser pulses with different transverse variations to obtain a more mildly focusing wake field. Work specific to conventional accelerators includes the discovery of nonlinear, integrable accelerator lattices, a method for calculating the equilibria of beams in such lattices, and the discovery of a photonic-crystal based accelerator cavity with reduced wake fields.
Professor Cary has been active in the IEEE, including helping organize the Particle Accelerator Conference, and in the Divisions of Physics of Beams (DPB) and Plasma Physics (DPP) of the American Physical Society, including being Chair of the APS-DPP.
Professor Cary received his doctorate from the University of California, Berkeley in 1979. He worked at the Los Alamos National Laboratory 1978-80, then the University of Texas 1980-1984. Dr. Cary joined the faculty at the University of Colorado in 1984, where he has been employed until the present. In 1994 Professor Cary co-founded (with Svetlana Shasharina Cary) Tech-X Corporation, which develops computational software for modeling accelerators and other physical systems.

Boulder, Colorado - February 15, 2017:
Researcher Yelong Wei used VSim to determine the quality of an electron beam from a dielectric dual grating structure, which is a proposed miniature particle accelerator. Particle accelerators are, in general, big and costly. The size and expense of particle accelerators is largely due to the limit of current RF cavity technology in terms of how much each cavity can accelerate particles without electrical breakdown. Extremely high particle energies are needed to explore fundamental subatomic processes. Dielectric laser-driven accelerators (DLAs) based on grating structures promise affordable, miniature particle accelerators that could be used by researchers in many different fields of scientific endeavor.
VSim simulates the complex interactions between beams, dielectric surroundings, and lasers, enabling researchers to extend the frontiers of current accelerators. Access the research paper Beam quality study for a grating-based dielectric laser-driven accelerator.
