AbstractSpace Solar Power System (SSPS) transfers enormous amount of electrical energy through microwave. Flight demonstration onboard a small satellite in Low Earth Orbit is now under consideration. When a high power microwave is irradiated from antenna in LEO plasma environment, there is a concern about multi-pactoring discharge caused by interaction between the plasma and the microwave. There has been no experimental observation on such interaction phenomenon. Verification experiment is essential for Space Solar Power System to become a reality.We have set-up an experimental system that can simulate the radiation of high power microwave in dense plasma in a vacuum chamber. A RF plasma source is installed to the chamber and can now produce the Argon plasma environment of 1x10(exp 14)m(exp -3) with 1eV temperature under a back pressure of 1.9x10(exp -4)Pa. A patch antenna with Teflon substrate has been installed inside the vacuum chamber. The antenna is connected to a magnetron that can produce 5.8GHz microwave up to 400W continuous power. Once the microwave intensity inside the vacuum chamber is confirmed, we will start the discharge experiment.
