Abstract :
The 200-BeV proton synchrotron being proposed by the Lawrence Radiation Laboratory is about 1 mile in diameter. The tolerance for accuracy in vertical placement of magnets is ±0.002 inches. Because conventional high-precision optical leveling to this accuracy is very time consuming, an alternative method using an extended mercury-filled system has been developed at LRL. This permanently installed reference system is expected to be accurate within ±0.001 in. across the 1-mile diameter machine.
