Caption courtesy D. Allan Bromley: "The Rochester 27 inch Cyclotron that was the basis for our conversion to variable energy. I personally machined the pole tips of the dipole dending magnet in the left foreground, made the sections of beam plumbing shown from brass piping, and the scattering chamber at the extreme left. The oscillator is behind the magnet and a high voltage electrostatic deflector was used to extract the beam into the external beam line. In the late 1950s this cyclotron was donated to a small university in India, where it remains in sporadic use to the present time [ca. 1996]. This photograph was taken in 1951."
