Shigeki Fukuda,M. Akemoto,Hitoshi Hayano,Hiroyuki Honma,H.Katagiri,S. Kazakov,S.Matsumoto,T. Matsumoto,S. Michizono,Hiromitsu Nakajima,Katsumi Nakao,Tetsuo Shidara,Tateru Takenaka,Yoshiharu Yano,Mitsuhiro Yoshida +14 more
TL;DR: The superconducting RF test facility (STF) at KEK has been operational since 2005, and STF Phase-I, which involves the testing of a cryomodule with four super-conducting cavities, was successfully completed at the end of 2008 as discussed by the authors.

TL;DR: In this paper, design considerations in the linac upgrade for SuperKEKB were reported. And the electron pre-injector was upgraded with a new electron-gun, the positron capture section was upgraded for higher positron intensity, and a positron damping ring was introduced to make a positron emittance sufficiently small.
High-intensity and low-emittance upgrade of 7-gev injector linac towards superKEKB

TL;DR: In this paper, the authors proposed a new asymmetric electron/positron collider, SuperKEKB, which aims at a luminosity of 8× 10 cm s, 40 times higher than that of KEKB, by mainly squeezing the beams at the collision point.
