Abstract:
A resonator (70) for resonating at a predetermined frequency in a linear accelerator (68), comprising:(i) a fixed position inductive coil (90) having a longitudinal axis (99), said coil having a first low-voltage end (94) and second high-voltage end (96);(ii) a radio frequency (RF) input coupled to said inductive coil;(iii) a capacitor (C.sub.S) electrically connected in parallel with said inductive coil; and(iv) a cylindrical drift tube (97) having a longitudinal axis (98) and being located at the high-voltage end (96) of the coil (90), said longitudinal axis (98) of said drift tube and said longitudinal axis (99) of said coil (90) being oriented substantially parallel to each other.
