# Three 300 kW, 108 MHz transistor amplifier systems

GSI Helmholtzzentrum für Schwerionenforschung GmbH seeks manufacture, delivery and installation of three compact, water-cooled 300 kW semiconductor power-amplifier systems operating at 108 MHz. The systems are to fit within no more than two cabinets and include local control; the mechanical layout must fit the existing site conditions.
