Description
In the fall of 1930, Professor Ernest O. Lawrence and his graduate student, M. Stanley Livingston, began developing this cyclotron, the first to accelerate ions. The 4 1/2 inch diameter chamber was placed between the poles of a 4-inch diameter magnet having a field of 12,700 gauss. The single dee carried 2000 volts. On January 2, 1931, this cyclotron produced 80,000 volt hydrogen molecular ions, trapped and measured in a Faraday cage.
