 KEK 



"Big Science" Descriptor ; High-energy physics 



Description of Facility/Instrument : This is a storage ring with a 

 positron beam that will collide with an electron beam, each 

 up to the 30 GeV energy level. A storage ring in which an electron 

 beam of 25 GeV can collide with a protron beam of 300 GeV is 

 planned.
