AGS modification

The Atomic Energy Commission has requested funds to modify the Brookhaven Alternating Gradient Synchrotron. The alterations are expected to take five years and will raise the AGS intensity to about $1013$ protons per pulse. Until the Soviet Union's 70‐BeV machine at Serpukhov is finished in 1967 or 1968, the AGS will continue to produce higher‐energy particles than any other machine on earth. The proposed 200‐BeV proton accelerator will not be in operation in the United States until 1975 at the earliest.
