8 GEV SYNCHROTRON RADIATION FACILITY PROJECT IN JAPAN - JAERI-RIKEN SPRING-8 PROJECT

Japan Atomic Energy Research Institute (JAERI) and the Institute of Physical and Chemical Research (RIKEN) are going to build an 8 GeV synchrotron radiation source in Harima Science Garden City of Hyougo Prefecture. The facility consists of an 8 GeV storage ring of 1436 m circumference with a natural emittance of 6.9 nm rad, an injector linac of 1 GeV and an 8 GeV synchrotron. Construction starts in 1990, and the first stored beam is foreseen in 1998. At the commissioning time 10 beam lines will be available while the remaining 51 beam lines, 32 on insertion devices and 19 on bending magnets, will be constructed successively. The facility will be open for use by the researchers of universities, national laboratories, and industries. It will also be open to foreign scientists.
