Lett. %R %P 461-464%V 12 %N 8 %U {https://cpl.iphy.ac.cn/CN/abstract/article_32934.shtml} %8 1995-08-01 %X We report some experimental results which confirm the theoretical analysis of the tuning feature of a reditron oscillator. Here, we produce high power microwave at 10 GHz, and the tuning range of the reditron is 8-13.32 GHz which is controlled by changing both the voltage and the anode-to-cathode separation. We also report a measurement method of the anode-to-cathode distance.
