Willard Harrison Bennett (
June 13 ,1903 –September 28 ,1987 ) was ascientist andinventor , born in Findlay,Ohio . Bennett conducted research intoplasma physics ,astrophysics ,geophysics ,surface physics , andphysical chemistry . TheBennett pinch is named after him.Biography
Born in
Findlay, Ohio , Bennett attendedCarnegie Institute of Technology from 1920-22 andOhio State University ; theUniversity of Wisconsin-Madison , Sc.M. in physical chemistry, 1926; and theUniversity of Michigan , Ph.D. in physics, 1928. Bennett was elected to a National Research Fellowship in Physics and in 1928 and 1929 studied at theCalifornia Institute of Technology . In 1930 he joined the Physics faculty at Ohio State. Following service inWorld War II , Bennett worked at the National Bureau of Standards, theUniversity of Arkansas , and theUnited States Naval Research Laboratory . In 1961, he was appointed Burlington Professor of Physics atNorth Carolina State University (emeritus in 1976). Bennett held 67patent s.Bennett made scientific history in the 1930s pioneering studies in "plasma physics - the study of gases ionized by high-voltage electricity". Bennett invented
radio frequency mass spectrometry in (1955). Bennett's radio frequency mass spectrometer measured the masses of atoms. It was the first such experiment in space. He also researched gases ionized by high voltage electricity. This research was used in laterthermonuclear fusion research.Invention impact
These studies and later research have been used throughout the world in controlled thermonuclear fusion research. In the 1950s, Bennett's experimental tube called the Stormertron predicted and modeled the
Van Allen radiation belt s surrounding the earth six years before they were discovered by satellite. It also reproduced intricate impact patterns found on the earth's surface which explained many features of the polar aurora.Sputnik 3 carried the first radio frequency mass spectrometer into space. It was the only space instrument used by the Russians and credited to an American inventor in their own Russian-language publications.External links
