Edwin McMillan and Edward Lofgren on the shielding of the Bevatron.

The Bevatron was a particle accelerator — specifically, a weak-focusing synchrotron — at Lawrence Berkeley National Laboratory which began operating in 1954. The antiproton was discovered there in 1955, resulting in the 1959 Nobel Prize in physics for Emilio Segrè and Owen Chamberlain. It accelerated electrons into a fixed target, and was named for its ability to impart energies of Trillions of eV. It was finally decommissioned in 1994. Image File history File links Bevatron. ...

Lawrence and His Laboratory: Chapter 6: Bumper Crop (3394 words)
Among the problematic features of the Bevatron's design was the size of the gap or aperture in which the magnets constituting the machine's backbone would confine the beam.
(The Bevatron actually built has four curved and four straight sections.) One straight section served to admit the proton beam from a small linear accelerator, which took its feed from a Cockcroft-Walton machine; in the final design, the particles gained 500 keV in the first stage of acceleration and another 9.5 MeV in the second.
Perhaps the farthest reaching of the discoveries made with the Bevatron were the so-called "resonances" or energies at which fleeting combinations of particles occur.
