High efficiency resonator for linear accelerator
 A new radio frequency (rf) linear accelerator (linac) is disclosed in this invention. The rf linac includes a plurality of resonators each includes an inductor circuit L(k), k=1,2,3, . . . , n' where n' is a second integer, wherein the inductor circuit connected to at least two electrodes E(j'), j'=1,2,3, . . . (n-1), for applying an accelerating rf voltage thereto. The rf linac further includes a plurality sets of transverse focusing lenses, represented by Lenses(j), where j=1,2,3, . . . n, and n is an integer, for guiding and focusing an ion beam. Each of the electrodes E(j') disposed between and aligned with two sets of the transverse focusing lenses Lenses(J') and Lenses(J'+1), j'=1,2,3, . . . (n-1), as a linear array. In a preferred embodiment, at least two of the adjacent electrodes E(j') and E(j'+1) are connected to a same inductor circuit L(k). In another preferred embodiment, at least two of the adjacent electrodes E(j') and E(j'+1) are connected to two different inductor circuits L(k1) and L(k2) where k1 and k2 are two different integers and k1 and k2 are smaller than n'. The energy gain from a resonator of this invention is twice or multiple of the energy gain from a single-electrode resonator with the same rf power efficiency.
