RFQ-Injector for HERA

For the HERA project at DESY an RFQ will be built as injector for a 20 mA H beam from 18 to 750 keV with a duty cycle of 10 U. The low average power and the moderate electrode voltage of 70 kV allows a flexible and simple design of the resonator. The design of the RFQ is described and the status of the project is discussed.
