Title: Photon factory: status of storage ring

Conference · · IEEE Trans. Nucl. Sci.; (United States)
OSTI ID:6785727

The 2.5 GeV electron storage ring at the Photon Factory is a dedicated synchrotron radiation source. The magnet system, composed of 28 bending magnets and 58 quadrupoles, is capable of raising energy up to 3 GeV by ramping after the beam is stacked. Injection is carried out in the multi-turn scheme at pulse times as long as 1 microsecond, a revolution time of 624 nanoseconds, and a rate of 1 Hz. Four 500 MHz RF cavities are situated in the straight section. Each cell is rated to dissipate 30 kW of RF power from an RF source consisting of two 180 kW klystrons. Out of 24 possible exit ports for synchrotron radiation, seven beam lines are operational and two more are in preparation. Each line is split into three or four branch lines, to each of which an experimental station is attached. The first beam was stored at the design energy in March 1982. Experiments in synchrotron radiation were begun in June. A superconducting vertical wiggler of 5 T and a permanent magnet undulator were successfully brought into operation in February 1983. This paper assesses the design and operating experience of the storage ring over its lifetime.
