In a previous blog post we congratulated our alum, David Pace (B.S. Physics 2002) for receiving the prestigious Landau-Spitzer Award given by the American Physical Society (APS) for his contributions to understanding the physics of plasmas and fusion.
Now Dr. Pace’s article, written with Drs. William W. Heidbrink and Michael A, Van Zeeland titled Keeping fusion plasmas hot is the feature story appearing on the October 2015 cover of Physics Today, the monthly professional journal of the APS. Pacific students and others on campus can access the article by clicking the title link above. Access is free through our library’s subscription when accessing the article from a computer on campus.
David is the first author of the article, which is about understanding the very complex interactions of plasma particles with the strong electromagnetic fields and waves inside the toroidal (bagel-shaped) fusion reactor, called a Tokamak. In the fusion reactions of deuterium and tritium, high energy alpha particles are produced which heat the plasma and help to maintain thermonuclear temperatures required for a self-sustained reactor. However, as the plasma heats, energetic ions can leak from the “magnetic bottle“, which can lower the reaction yield, ablate material from the tokamak walls polluting the plasma, and even damage the reactor vessel.
The article in Physics Today reviews David’s and his collaborator’s work on understanding these complex wave-particle dynamics that will help researchers better control this energy loss mechanism in reactors such as the International Thermonuclear Experimental Reactor (ITER) currently under construction in the south of France. In fact, if you visit ITER’s website, David’s article is featured as one of the rotating header images/links for the international project.
Wow! Cover of Physics Today AND the top of the ITER webpage!
Congratulations Dr. David Pace from all of us here at UoP!
I expect it won’t be long before David’s picture is on the “cover of the Rolling Stone”.
(for my students, that’s a reference to a 70’s song by Dr. Hook, from when I was your age).
