Description: 

Calutron operators at an electromagnetic isotope separation plant in Oak Ridge during World War II.  Calutrons were overgrown mass spectrographs used to separate isotopes.  The name is an acronym for 'California university cyclotron.' Note the supervisor standing near the end of the row; neither he nor anyone else in the picture had any idea of the purpose of their labor, save that it was 'vital to the war effort.' Many women graduates from East Tennessee high schools tended the Y-12 control panels.  Each operator monitored two control panels.
