  Asymmetrical Alternate Phase (A-APF) focusing realized in a sequence of 36
Superconducting Quarter Wave Resonators has been shown to accelerate almost 81
% of input Uranium beam before foil stripper to an energy of 6.2 MeV/u from 1.3
MeV/u. Ten charge states from 34+ to 43+ could be simultaneously accelerated
with the phase of resonators tuned for 34+. A-APF structure showed unique
nature of large potential bucket for charge states higher than that of tuned
one. Steering inherent to QWRs can be mitigated by selecting appropriate phase
variation of the APF periods and optimization of solenoid field strengths
placed in each of the periods. This mitigation facilitates multiple charge
state acceleration scheme
