On that clay the country lost one of its most influential physicists, one with a remarkable breadth of interests. Kerst will long be remembered for his clevelopment of the betatron, but he also macle very important contributions to the general design of particle accelerators, nuclear physics, medical physics, and plasma physics.

, to a preliminary analysis of all conceivable effects relevant to the operation of a betatron, and to a careful and detailed design of the magnet structure, vacuum system, and power supply. This was the first new accelerator to be constructed on the basis of a careful scientific analysis and a completely engineered design.

War II clays, Kerst built a 4-M eV portable betatron for inspecting bomb clucis in situ and, most importantly, built a 20-MeV betatron at Los Alamos for stucly of bomb assembly implosions. His work was clescribec!

In addition, we have profited by letters of nomination written through the years for the Enrico Fermi Award and the National Medal of Science by Keith Symon and Heinz Barschall. We found most informative an article titled, "Historical development of the betatron" tNature (LondonJ 157~1946~:90]
