The Bevatron Reactivated

The Bevatron at the Lawrence Radiation Laboratory returned to service in mid‐February after being shut down since June of last year for major overhaul and modifications. The modification program, which began in 1960, was carried out under the direction of Edward J. Lofgren, physicist in charge of the Bevatron, and was completed on schedule. The alterations were financed by the Atomic Energy Commission at a cost of $9.6 million, which is approximately equal to the original investment in the machine, and they were directed primarily toward improvement of beam intensity and control. Although the peak energy of the primary beam protons remains the same (6.2 BeV), the intensity at present is ${\text{8×10}}^{11}$ particles per pulse, four times the original beam intensity, and potentially it may be raised to 25 times the earlier level.
