Abstract :
The Drossel collaboration was established for the development a low emittance, high average current, cw electron injector suitable for the ELBE project. The injector is based on a photocathode RF gun with a superconducting cavity. A half-cell 1.3 GHz superconducting niobium cavity incorporated with a normal conducting cathode unit was designed and produced to check the basic design concepts. Cold RF tests of the cavity at T=2 K were successfully carried out at DESY TTF. Now preparation of the necessary components for the beam tests is in progress
