Plural of betatron; multiple particle accelerators that use magnetic fields to accelerate electrons and produce intense radiation.
Regular English plural of 'betatron,' formed by adding '-s.' The singular term originated in physics laboratories in the 1940s as scientists named their new technology.
Hospital physics departments in the 1950s-70s had rooms full of betatrons—their presence marked the moment medicine became dependent on extreme particle physics, turning cancer treatment into an atomic-age endeavor.
