This paper describes an application of microwave discharge ion thruster to remote sensing for upper neutral atmosphere. We assume the charge exchange collision between atomic oxygen (AO) and krypton ion beam. An apparatus has been constructed to simulate the atomic oxygen in an upper neutral atmosphere. From the experimental results, the gas density was subtle to detect ENA through CEX sell. Therefore, the apparatus variant was proposed.
