Zero Gradient Synchrotron 12
II: Buildings and Grounds
Partially assembled ring magnet octant undergoing alignment. Each of the magnet blocks is composed of half-inch sections of steel bonded together with fiberglass and epoxy resin. The blocks are bolted together and sealed. The gap in the magnet is for installation of the vacuum chamber, a stainless steel doughnut 5-3/4 inches high, 32 inches wide, and 200 feet in diameter. The Zero Gradient Synchrotron is a high intensity machine because of the large size of this chamber, thus more protons can be injected into the machine than any other because of the space available. The radio-frequency cavity which accelerates the protons in the ZGS is in the background. Protons pick up speed from the 20,000 volt kick they receive each time they traverse it, and its frequency varies from 4 to 14 Megacycles per second. The beam enters the ring from the linac through the tunnel whose opening can be seen just to the right of the radio-frequency station.
