Injection into the two MAX IV storage rings will not make use of a 4-kicker local injection bump. Instead, pulsed multipole injection will be used for initial filling as well as top-up injection. Since commissioning a pulsed multipole magnet for injection into a storage ring is non-trivial, it has been decided to install a single dipole kicker magnet into the storage rings to provide a simple method for injection during early commissioning. Design studies have revealed that injection with a single dipole kicker into the MAX IV storage rings is not only efficient, but also allows for accumulation of beam. Although this accumulation cannot be made transparent to users (i.e. it is not compatible with user top-up operation), it does provide a simple and robust injection method during commissioning. In addition, the dipole kicker can be used as a pinger magnet during machine studies with a single-bunch filling. This paper reports on the design studies performed for dipole kicker injection into the MAX IV storage rings and presents a summary of the expected performance of such an injection scheme.
