Polarimetric observations of comet Levy 1990c and of other comets: Some clues to the evolution of cometary dust [PDF]
The evolution with the phase angle alpha of the polarization degree P of light scattered by comet Halley's dust is well documented. No significant discrepancy is found between Halley and Levy polarization curves near the inversion point.

Extended performance solar electric propulsion thrust system study. Volume 4: Thruster technology evaluation [PDF]
Several thrust system design concepts were evaluated and compared using the specifications of the most advanced 30 cm engineering model thruster as the technology base. Emphasis was placed on relatively high power missions (60 to 100 kW) such as a Halley'
