Batavia accelerator reaches 200 GeV

Now that the Batavia accelerator has reached its design energy of 200 GeV (on 1 March), physicists can breathe a sigh of relief, although considerable effort remains to be expended before the machine operates at full intensity. Director Robert R. Wilson had hoped to bring the accelerator into operation a year early, in mid‐1971 (PHYSICS TODAY, June 1970, page 29) and soon after to raise the energy to 500 GeV at reduced intensity.
