An earlier report, "A Proton Synchrotron for 300 Gev,"1 has shown that a 300 Gev Alternating Gradient Synchrotron could be operated if the magnets could be positioned, and held in position, well enough so that the short range random derivations of the magnets from a circle would be less than 0.1 mm. A misplaced magnet tends to deflect the orbit of the beam of protons and a series of errors in the placement of the magnets can very well deflect the beam out of the vacuum tube aperture. Two A.G. synchrotrons with l/8th mile diameters have been constructed to similar tolerances and the drift of the magnets of one of them, the CERN P.S., in the first month of operation, was sufficiently small that it did not affect the beam. The question is whether it is indeed possible to achieve and maintain the same tolerances for a machine that is 1.6 miles in diameter. From the preliminary study on which this report is based, it appears that the same techniques of surveying and foundation design that were used for the A.G.S. and the P.S. will provide the desired precision and stability.
