Abstract

The laser-driven in-tube accelerator (LITA) is a unique concept of laser propulsion. It is characterized by accelerating an object in a tube. Owing to a confinement effect, the thrust performance can be improved. This device has other advantages over the existing technology on the simplicity and suitability to environment. Experiments on the thrust performance of LITA were conducted. The thrust was determined from the object hovering condition. The measured dimensionless momentum coupling coefficient agrees between xenon and argon as the working gas. This implies that in order to obtain a high impulse chemical species with a low speed of sound is useful.
