Nicholas Christofilos and the Astron Project in America's Fusion Program
Elisheva Coleman May 4, 2004 Spring Junior Paper Advisor: Professor Mahoney Greek Fire: Nicholas Christofilos and the Astron Project in America’s Fusion Program This paper represents my own work in accordance with University regulations The author thanks the Program in Plasma Science and Technology and the Princeton Plasma Physics Laboratory for their support. Introduction The second largest building on the Lawrence Livermore National Laboratory’s campus today stands essentially abandoned, used as a warehouse for odds and ends. Concrete, starkly rectangular and nondescript, Building 431 was home for over a decade to the Astron machine, the testing device for a controlled fusion reactor scheme devised by a virtually unknown engineer-turned-physicist named Nicholas C. Christofilos. Building 431 was originally constructed in the late 1940s before the Lawrence laboratory even existed, for the Materials Testing Accelerator (MTA), the first experiment performed at the Livermore site.1 By the time the MTA was retired in 1955, the Livermore lab had grown up around it, a huge, nationally funded institution devoted to four projects: magnetic fusion, diagnostic weapon experiments, the design of thermonuclear weapons, and a basic physics program.2 When the MTA shut down, its building was turned over to the lab’s controlled fusion department. A number of fusion experiments were conducted within its walls, but from the early sixties onward Astron predominated, and in 1968 a major extension was added to the building to accommodate a revamped and enlarged Astron accelerator. As did much material within the national lab infrastructure, the building continued to be recycled. After Astron’s termination in 1973 the extension housed the Experimental Test Accelerator (ETA), a prototype for a huge linear induction accelerator, the type of accelerator first developed for Astron. -

Marcos Moshinsky Kiev, Ukraine, 20 Apr
Marcos Moshinsky Kiev, Ukraine, 20 Apr. 1921 - Mexico City, Mexico, 1 Apr. 2009 Nomination 9 June 1986 Field Physics Title Professor at the Universidad Nacional Auto#noma de Me#xico Commemoration – The impressive biographical data of Marcus Moshinsky is very well documented in the Yearbook that we have in front of us, so I think there’s no sense in reading it to you. I think I can do justice to his genius better by telling you my personal recollections on four encounters with his work, which show the breadth of his intellectual horizon. The first was very long ago in 1951. I was in Gottingen and there appeared a paper in Physics Review which derived the essential consequences of general relativity just by solving the Schrödinger Equation in an external gravitational potential, and we were very perplexed. It was not talking about the non- Euclidian geometry, and it came from Princeton, where Einstein was still alive and dominating. The paper sort of said that, actually, we don’t need Einstein, we can derive all this very simply. We tried to find a mistake, as there were many crazy theories around, but we couldn’t find anything so we decided it was correct. Then we didn’t know what to do, since he had apparently found an effect which is present, as is the one of general relativity, so perhaps you should add them since both are correct. But if you do that then you get a factor 2 and destroy all the agreement with the experiment, so that’s not what you want to do. -
