摘要

A fundamental study on laser-electrostatic hybrid acceleration thruster was conducted, in which laser-induced plasmas were induced through laser beam irradiation on to a solid target and accelerated by an electrostatic field of an acceleration electrode. Also, a fundamental relativistic consideration of thrust performance for the high-specific-impulse thrusters was conducted. For thrust measurements, a calibrated torsion-balance type thrust-stand was developed and utilized. A time-of-flight measurement with a Faraday cup was also conducted for ion current and velocity measurements. It was shown that an acceleration electrode with positive potential was more effective than that with negative potential for positive-ion acceleration in the laser induced plasma, in which ions were induced with the Coulomb explosion.
