The KEKB filling-pattern generating system

Abstract

KEKB is a high-luminosity electron-positron collider, consisting of an 8 GeV electron ring and a 3.5 GeV positron ring. To achieve the required luminosity, beams are squeezed to become very sharp and a large number of particles are stored in the rings. In order to operate the KEKB rings smoothly under a very high-current environment, we developed a user-friendly filling-pattern generating system. With the help of high-speed bunch-current measuring systems, it contributed to the stable operation of the collider rings. © The Author(s) 2013.
