Beam Based Measurement of Injection Parameters at KEKPF

摘要

Photon Factory storage ring (PF-ring) is the 2.5 GeV synchrotron radiation light source in KEK. After the earthquake hit in 2011, the injection efficiency using the conventional pulsed kicker and septum system has decreased. The primary cause of the problem seems to be the change of the injection parameters. To analyze the present injection parameter, we carried out the simulations [1] and beam studies. In this paper, we show the beam based estimation of the position and divergence angle of the injected beam at the exit of the injection septum magnet.
