Abstract

Future light sources aim at achieving a diffraction limited photon beam both in the horizontal and vertical planes. High gradient quadrupoles and strong chromaticity correction sextupoles in a corresponding ultra-low emittance ring may restrict the physical and dynamic aperture of the storage ring such that off-axis injection and accumulation may become impossible. We propose a longitudinal injection scheme, i.e., injecting an electron bunch onto the closed orbit with a time offset with respect to the circulating bunches. The temporal separation enables a pulsed dipole kicker to situate the injected bunch transversely on-axis without disturbing the circulating bunches if the pulse length is shorter than the bunch spacing. The injected bunch is finally merged to a circulating bunch through synchrotron radiation damping. We present the scheme in detail and its application to the lattice of the MAX IV 3 GeV storage ring. The requirements and feasibility of the pulsed dipole kicker are also discussed.
