Hochfrequenz-Photoelektronenquellen mit supraleitenden Resonatoren (SRF-Gun) besitzen das Potential Elektronenstrahlen exzellenter Qualität und mit hohem Strahlstrom zu liefern, die für zukünftige Lichtquellen benötigt werden. An der Strahlungsquelle ELBE ist eine solche Quelle seit 2007 in Betrieb. In den vergangen Jahren wurde eine verbesserte Version (ELBE SRF-Gun II) entwickelt. Im Mai 2014 wurde die SRF-Gun II am Beschleuniger installiert. Das Poster stellt diese Elektronenquelle vor und berichtet über die Inbetriebnahme.

At the Forschungszentrum Rossendorf the build-up of the superconducting 1.3 GHz accelerator ELBE is still in progress. Furthermore a new sc photo injector (SRF gun) is under development, which should accelerate electrons up to 10 MeV at 1.3 GHz frequency. The use of electron accelerators is also more and more interesting for applications where the destructive potential of the electrons are used like sterilization of medical waste and medical products, food irradiation or decontamination of sewage. For these processes a high power is required to achieve a high product throughput in a plant. The aim is therefore to use beam powers of around 100 kW or more. Since the applications of electron accelerators in industrial environments are steadily increasing one can speculate about transferring the above named state of the arte technology to industrial electron accelerators. At the FZR a feasibility study of such a table top electron accelerator (TTE) has been performed to investigate its technical limits and marketabilitys.
