At Clinton Engineer Works -Tennessee Eastman Corporation, a mass spectrograph was operated in an evacuated tank between the pole faces of a large electromagnet to separate the isotopes of uranium. The mass spectrograph consisted of an ion source, an accelerating-electrode system to draw the ions at uniform velocity into the evacuated space, a liner to define a space of uniform electric-field intensity through which the ions passed, and a receiver to collect the separated isotopic ions. The source was operated at a potential positive with respect to the liner part of the accelerating-electrode system was operated at a potential negative with respect to the liner and the liner and receiver both operated at the same potential. Quantity production of these isotopes necessitated high currents to maintain the desired potentials, and the voltage applied necessitated rigid protection measures.
