Abstract

Ground-Based Research Program for Space Utilization promoted by the Japan has developed a laser-driven in tube accelerator for launching an object using repetitive laser pulse ablation. The used laser pulse is backed by the moderately confined space in the tube that is useful for obtaining a large impulse with a moderate acceleration level on the order of the gravitation. The study has used a 25-mm-inner-diameter, 1-m-long acrylic cylinder as the vertical launch tube, with a lower end plugged by a piece of ZnSe window to send laser pulses. The study has also evaluated the launch performance within a limited number of laser pulses. The muzzle of the launcher can be open, even to vacuum and that the impulse performance can be increased by further increasing the length of the launch tube. The impulse performance can also be increased by further increasing the launch-tube length.
