Acceleration strategy for compact storage rings with low energy injection scheme

The acceleration strategy for an accelerator with a low energy injection scheme (LEI) is investigated. The space charge octupole-like effect caused by the electron beam and trapped ions plays an important role in beam injection and acceleration. We present an acceleration method that makes it possible for Super-ALIS, a superconducting compact storage ring, to achieve a stored current of over 200 mA with injection at 15 MeV.
