Alpha Track Calutron at the Y-12 Plant at Oak Ridge, Tennessee from the Manhattan Project, used for uranium enrichment.

Control panels and operators for calutrons at the Y-12 Plant in Oak Ridge, Tennessee. During the Manhattan Project the operators worked in shifts covering 24 hours a day.

Design of the receiver for the alpha calutron. Uranium- 235 collects in the small pocket between.

The "C" shaped alpha calutron tank, together with its emitters and collectors on the lower-edge door, was removed in a special "drydock" from the magnet for recovery of uranium-235.

A vast bank of diffusion vacuum pumps operated underneath the alpha calutron racetrack to free the tanks of air.

Description Frank Oppenheimer (center right) and Robert Thornton (right) examine the 4-source emitter for the improved alpha calutron.
