Early Commissioning of the Luminosity Dither Feedback for SuperKEKB
/ Masuzawa, Mika (KEK, Tsukuba) ; Bambade, Philip (Orsay, LAL) ; Brown, David (SLAC) ; Di Carlo, Salvatore (Orsay, LAL) ; El Khechen, Dima (CERN) ; Fisher, Alan (SLAC) ; Funakoshi, Yoshihiro (KEK, Tsukuba) ; Jehanno, Didier (Orsay, LAL) ; Kawamoto, Takashi (KEK, Tsukuba) ; Nakamura, Shu (KEK, Tsukuba) et al.
SuperKEKB is an electron–positron double ring collider that aims to achieve a peak luminosity of 8 x 10$^{35}$ cm$^{-2}$ s$^{-1}$ by using what is known as the “nano-beam” scheme. A luminosity dither system is employed for collision orbit feedback in the horizontal plane. [...]

Achievements of KEKB
/ Abe, Tetsuo (KEK, Tsukuba) ; Akai, Kazunori (KEK, Tsukuba) ; Akasaka, Norimasa (KEK, Tsukuba) ; Akemoto, Mitsuo (KEK, Tsukuba) ; Akiyama, Atsuyoshi (KEK, Tsukuba) ; Arinaga, Mitsuhiro (KEK, Tsukuba) ; Cai, Yunhai (SLAC) ; Ebihara, Kiyokazu (KEK, Tsukuba) ; Egawa, Kazumi (KEK, Tsukuba) ; Enomoto, Atsushi (KEK, Tsukuba) et al.
The machine commissioning of KEKB started in December 1998 and its operation was terminated at the end of June 2010 to upgrade KEKB to SuperKEKB. In this paper, we summarize the history of KEKB and show the achievements made there..
