The objective of this investigation is to measure the plasma flow around Comet Halley in order to study (1) the mass loading of the solar wind by ions of cometary origin, (2) the existence, location, and strength of the upstream shock transition in the solar wind flow, (3) the position of and forces controlling the pressure balance surface between the cometary and the solar plasma, (4) the processes that form tail rays and other discrete visible features in the coma, and (5) the detection of wave motion induced by the cometary interaction that leads to the thermalization of solar wind and implanted ions. The instrument employs two sensors. One is a 270-deg spherical electrostatic energy analyzer (EEA) with a microchannel plate detector that... ...Show More
