Abstract

SAGA Light Source is a synchrotron radiation source, which consists of 250MeV injector linac and 1.4GeV storage ring, located in northern Kyusyu, Japan [1]. The beam transfer line from the linac to the ring consists ob a 40-degree bending magnet, a 20-degree bending magnet, two quadrupole doublets and a quadrupole singlet. The bump orbit is generated by four-kickers which are excited by sinusoidal electric currents with a half width of 1μs. We have performed injection tracking studies using TRACY2 [2] to confirm the angle and energy injected beam acceptance. It has been found that the angular acceptance for the injection beam is from -3.5mrad to +2.5mrad and the energy acceptance is 1%.
