The superconducting CH-cavity is an excellent candidate for the efficient acceleration in high power proton and ion drivers like EUROTRANS (EUROpean Research Programme for the TRANSmutation of High Level Nuclear Waste in an Accelerator Driven System, 600 MeV 352 MHz) and IFMIF (The International Fusion Material Irradiation Facility, 40 MeV 175 MHz). The CHstructure is a superconducting cavity for the low and medium energy range operated in the H₂₁-mode. A prototype cavity has been developed and tested successfully with a gradient of 7 MV/m. Presently a new superconducting CH-cavity with improved geometry for these high power applications is under construction. The status of the cavity development related to EUROTRANS and IFMIF is presented.
