摘要We present an improved structure of the tapered magnetically insulated transmission line oscillator (MILO). Simulation results show that this structure can obtain more microwave power with higher efficiency. Studies indicate that the distance between the load support legs and the last vane can affect the operation characteristics of this device. In the experiments, we obtain microwave with peak power of 2GW, frequency of 2.63GHz, and mode TM01. The beam to microwave power efficiency is 11%.
