Abstract
As the beam envelope mismatch is the major source of the halo formation and the related emittance growth in high intensity linac, some extensions based on the four-step method are developed, and the causes of beam mismatch in RFQ are analyzed and a matching dynamics method is proposed to minimize the emittance growth and the related beam loss. A dynamics example is given to prove this design method.
