抄録	Pulsed Plasma Thrusters (PPT) are electrothermal and electromagnetic thrusters to produce thrust in a discharge. A coaxial PPT with solid propellant has been designed and operated in Gifu University. To examine unsteady characteristics in the discharge process of the PPT, measurements using a high speed camera and a triple Langmuir probe were carried out. The time variances of luminescence form the PPT were observed for various cavity geometries. As a result, a strong correlation was observed between the intensity of the luminescence and the cavity geometry. Measurements of the PPT using photosensors for the luminescence geometries were performed using a photosensor system incorporating optical fibers, which was developed in this study. As a result, it was found that difference in the time lag of the exhaust plasma behind the discharge current peak for all cavity geometries depended on the distance from the nozzle.
