Performance tests in 100-hr range were conducted for 100-μlb thruster modules at average specific impulses ranging from 577 to 1135 sec; new thruster configurations (bipolar self-neutralizing, linear slit, and high-voltage thick needle) were investigated; 50-μlb bipolar module has been run for two 50-hr tests at specific impulses of 700 and 800 sec; complete microthruster flight system is developed for yaw control of synchronous satellite; one thruster module for system has accumulated 1500-hr operation (820 hr continuous) in 800-sec specific impulse range with no degradation; direct transverse thrust measurements of electrostatically deflected colloid beam were taken to demonstrate thrust vector control capability.
