Summary
Short zero degree synchronous particle structures and magnetic focusing lenses can be combined in such a way that the emittance of each section is well adapted to the acceptance of the following section. By that way drift tube linacs can do the particle acceleration more close to the crest of the RF wave, the transverse RF defocusing effect can be minimized and the emittance growth of the beam is kept low. Specific problems of the heavy-ion fusion linacs are the acceleration of 1+charged ions with mass numbers around 200 and beam currents around 100 mA. This paper investigates the suitability of theInterdigitalH-type structure for that application. Technical as well as beam-dynamical aspects and the beam-cavity interaction are discussed.
