Conventional magnetic transverse focusing in conventional linacs represents a high fraction of their cost and complexity. Both transverse and longitudinal focusing can be obtained from the rf field by using the strong-focusing effect of alternating patterns (sequences) of gap phases and amplitudes – known as Alternating-Phase-Focusing (APF). Although studied for decades, the difficulty of designing suitable sequences has inhibited APF adoption, although short sequence APFs are now used in a number of practical applications. Synthesis of reported details and new physics and technique result in a new, general and efficient method for designing APF linacs. Very long sequences with high energy gain factors are demonstrated, e.g. for acceleration of very cold muons from ~0.340-200MeV (factor 600).
