The redesigned electron synchrotron at the California Institute of Technology is now able to operate at its maximum energy of 1.5 Bev, according to an announcement by Robert F. Bacher, director of the synchrotron project and chairman of Caltech's Division of Physics, Mathematics, and Astronomy. It is the only electron accelerator in the world with beam energies covering the range from 1.2 to 1.5 Bev. The latter energy yields a velocity of 99.999995 percent of the speed of light for the orbiting electrons.
