Slepian did significant groundwork for the betatron (1927). In particular, Touschek conceived the idea of radiation damping for electrons circulating in a betatron. Early work centered on research with a Betatron. A non-scaling FFAG allows a quantity known as the betatron tune to vary unchecked. The betatron would influence all subsequent accelerators. He also designed a portable 4 MeV betatron for inspecting dud bombs. The result of these efforts was the betatron. A betatron is a type of cyclic particle accelerator. Therefore, he worked at the Betatron in Turin and then at the Synchrotron in Frascati. A 3 MeV betatron was converted an 18 MeV electron synchrotron in 1948. In 1948, the university built the first betatron facility in Canada. His early research involved perfecting GE's 100 MeV Betatron for use as an x-ray source. On January 15, 1945, the G-5 Group took their first betatron pictures of an implosion.
