In December 1941 Kerst decided on " betatron ", using the Greek letter " beta ", which was the symbol for electrons, and " tron " meaning " instrument for ".

In 1945, at the invitation of the Rockefeller Foundation, Damy spent nine months at the University of Illinois . where he worked with Prof . Donald William Kerst, inventor of the betatron.
23.
The betatrons were still at the plant in late 1992 " in a building on the southern section of the plant property " The building " had residual radioactive contamination until remediation in 1993 ."
24.
He went on to build more betatrons of increasing energy, a 20 MeV machine in 1941, an 80 MeV in 1948, and a 340 MeV machine, which was completed in 1950.

The first clinical use of the high energy Betatron radiation for medical therapy proved beneficial to effectively reduce the mass of the tumor, yet not sufficient to eliminate the tumor and provide a cure.
26.
The Radiation Center, the first private medical center to treat cancer patients with a betatron, was opened by Dr . O . Arthur Stiennon in 1957 in Doctors'Park at 2716 Marshall Court.

"' Rolf Wider�e "'( 11 July 1902 11 October 1996 ), was a particle acceleration concepts, including the " resonance accelerator " and the betatron accelerator.

Returning once again to Brazil, Damy accepted an assistant professorship at the Department of Physics of USP, and helped install there in 1950 a betatron, the first particle accelerator operating in Latin America.
29.
The Radiation Center, the first private medical center to treat cancer patients with a betatron, was opened by Dr . O . Arthur Stiennon in a suburb of Madison, Wisconsin in the late 1950s.

During World War II, Kerst took a leave of absence in 1940 and 1941 to work on it with the engineering staff at General Electric, and he designed a portable betatron for inspecting dud bombs.
