Abstract
A 25.5 MHz double-coaxial lambda/4-resonator has been constructed to be use d as a rebuncher between a 25.5 MHz RFQ linac and a 51 MHz interdigital-H l inac for the acceleration of short-lived nuclei. By employing a double coax ial structure, the resonator length is only 130 cm; the length of the natur al lambda/4-resonator is 294 cm. The resonator, 69 cm in inner diameter, ha s six acceleration gaps. The bare shunt impedance is 40.6 M Omega/m. The io ns with a charge-to-mass ratio 1/10 can be rebunched by feeding an rf power of 1.4 kW. (C) 1999 Elsevier Science B.V. All rights reserved.
