Title :
The IH-structure and its capability to accelerate high current beams

Abstract :
The longitudinal and transversal acceptance of the original Munich cavity type was enlarged, and an improved type of IH cavity was developed and constructed. It consists of sections for acceleration, transversal focusing, and longitudinal focusing. The 108-MHz GSI cavity contains three structure periods of that kind and accelerates the design ion /sup 238/U/sup 25+/ from 300 keV to 1.4 MeV/u. Results from RF power tests and the status of the IH cavity for the 1.4-MeV/u UNILAC injector are reported. Basic considerations and investigations about the designs for the acceleration of higher beam currents are described.<>
