Alain Brizard, professor of physics, was “host” during a rare partial solar eclipse as experienced by nearly 100 Saint Michael’s people around his small telescope set up by the large clock on the main campus green on Aug. 21. Many donned special glasses to view the eclipse. Alain brought out his 40-year-old, personal 3.5-inch Questar telescope and set it up on a table at the site around 1 p.m., shortly after the moon first started to visibly move over the sun, and stayed till the eclipse was over several hours later.

Alain Brizard, professor of physics, during a sabbatical leave in the 2017 spring semester, has taught a short course in gyrokinetic theory at the Institute for Fusion Theory and Simulation at Zhejiang University in Hangzhou (China), April 10-21,the Department of Applied Physics of Aalto University in Espoo (Finland), May 1-18, and the Max Planck Institute for Plasma Physics in Greifswald (Germany), June 12-24. These short courses were or will be taught to graduate students and postdocs as part of his work in writing a graduate-level textbook on gyrokinetic theory (to be published by World Scientific later this year). In the past two years, Alain has published seven peer-reviewed articles with collaborators both in the US and abroad in Physics of Plasmas, the Journal of Plasma Physics, and Communications in Nonlinear Science and Numerical Simulation (with an undergraduate math major at Saint Michael’s). In 2016-2017, he also presented nearly 20 seminars, invited talks, and contributed presentations at national and international conferences.

Alain Brizard, professor of physics, had two articles accepted for publication in the peer-reviewed journal Physics of Plasmas: "Monte Carlo implementation of a guiding-center Fokker-Planck kinetic equation" in a collaboration with physicists from Aalto University (Finland); and "Beyond linear gyrocenter polarization in gyrokinetic theory." A third publication, "Exact conservation laws for the truncated gyrokinetic Vlasov-Poisson equations," in a collaboration with N. Tronko (York Plasma Institute, UK), also was published in the Proceedings of the 40th European Physical Society Conference on Plasma Physics (held in Helsinki, Finland, in June 2013). Alain's second textbook, Ray Tracing and Beyond: Phase-space Methods in Plasma Wave Theory, written in collaboration with A.N. Kaufman (Berkeley), E.R. Tracy (William and Mary), and A.S. Richardson (Naval Research Lab), was submitted to Cambridge University Press (with a tentative release date of January 2014). Lastly, Alain gave a seminar, "Guiding-center effects in gyrokinetic momentum conservation laws for axisymmetric tokamak plasmas," at the Princeton Plasma Physics Lab on August 22.
Alain Brizard, professor of physics, had two papers accepted for publication this summer: "Action-angle coordinates for the pendulum," to be published in Communications in Nonlinear Science and Numerical Simulation, and comment on "Geometric phase of the gyromotion for charged particles in a time-dependent magnetic field" (with Loic de Guillebon), to be published in Physics of Plasmas. Alain also presented the seminar "Beyond linear polarization in gyrokinetic theory" at the Princeton Plasma Physics Laboratory (Princeton University) on July 31, 2012, and the Center for Theoretical Physics Luminy (Marseille, France) on July 18, 2012. Lastly, he submitted the following manuscripts for publication in Physics of Plasmas: "Gyrokinetic momentum conservation in truncated gyrokinetic Vlasov-Maxwell theory" (with Natalia Tronko, CFSA, Warwick University, UK), "Equivalent representations of higher-order Hamiltonian guiding-center theory" (with Natalia Tronko, CFSA, Warwick University, UK), and "Hamiltonian formulation of reduced Vlasov-Maxwell equations" (with Cristel Chandre and Emanuele Tassi, CPT Luminy, France).
