HIGH FREQUENCY GENERATION DEVICE

PURPOSE:To obtain a high frequency generation device making it possible to recover energy with a constitution except a multistage constitution by providing the back of a heat receiving surface of the collector part with a cathode for generating thermal electrons and the collector to convert thermal energy of a spent beam into electric power by using thermal electron power generation for its recovery. CONSTITUTION:The back of the heat receiving surface of a collector 12 is a thermal electron generation cathode 30 while a cesium store 24 between the cathode 30 and the thermal electron generation connector 31 is filled with cesium vapor. Thermal electrons generated from the cathode 30 reach the collector 31 to generate DC power. Said DC power is converted into AC power by a converter 25 to be transformed into appropriate voltage by a transformer 26 for being taken out. Thereby, a spent beam is once converted into thermal energy before being used.
