Lecture Series No. 45 – Accelerator Physics and Technology

Lecturer：Prof. Yoshihiro Funakoshi, KEK,Japan

Chair：Dr. Weiren Chou, FNAL, USA/IHEP

Theme：Overview of SuperKEKB, issues and commissioning plan

Time： 14：00 (April 11, 14:00)

Place： Hall No.5, Meeting Room

Abstract：

KEKB collider recorded the world highest luminosity 2.1？1034 cm-2s-1. The KEKB operation was terminated in June 2010, and it is under a major upgrading phase to becomeSuperKEKB. The target luminosity of SuperKEKB is 40 times higher than that of KEKB or8？1035 cm-2s-1. The target integrated luminosity is 50 ab-1. It is expected to collect this target luminosity by 2023 in the present scenario. In this lecture, Dr. Funakoshiwill show the concept of SuperKEKB, the issues which have been discussed at KEK and the commissioning plan which is expected to start in January 2015.

Lecturer’s short bio:

At KEK, the speaker worked and will work at 3 machines, TRISTAN, KEKB and SuperKEKB. His main duty has been the beam operation. The speaker was in charge of beam operation of KEKB and will also be in charge of beam operation (or commissioning) of SuperKEKB. As other works, he developed an orbit feedback system to maintain the optimum collision condition at KEKB and conducted various machine studies at TRISTAN and KEKB.
