Abstract

The cross-bar H-type (CH) cavity is a multigap drift tube structure based on the H-210 mode currently under development at IAP Frankfurt and in collaboration with GSI. By use of the KONUS beam dynamics long lens free sections can be realized, making the design of a superconducting multicell CH resonator possible. Numerical simulations and RF model measurements showed that the CH-type cavity is an excellent candidate to realize s.c. multicell structures ranging from the RFQ exit energy up to the injection energy into elliptical multicell cavities. The reasonable frequency range is from about 150 MHz up to 800 MHz. A 19-cell, β=0.1, bulk niobium prototype cavity is under construction at the ACCEL-Company, Bergisch-Gladbach. This paper will present detailed MicroWave Studio simulations of the superconducting CH cavity.
