Walton, Ernest Thomas Sinton (1903-1995), an Irish physicist, shared the 1951 Nobel Prize in physics with Sir John Cockcroft. They discovered jointly the transmutations of atomic nuclei by artificially accelerated particles in 1932. They constructed the first of the controlled particle accelerators, producing 500,000 volts. Their experiments confirmed Albert Einstein’s theory that mass and energy are equivalent. Walton was born on Oct. 6, 1903, in Dungarvan. He died on June 25, 1995.
