The Plasma and Suprathermal Ion Composition (PLASTIC) investigation provides the in situ solar wind low energy heliospheric ion measurements for NASA Solar Terrestrial Relations Observatory Mission, which consists of two spacecraft (STEREO-A, STEREO-B). PLASTIC-A PLASTIC-B are identical. Each PLASTIC is a time-of-flight/energy mass spectrometer designed to determine elemental composition, ionic charge states, bulk flow parameters major ions range from hydrogen iron. has nearly complete...
As expected, a wide range of ion species and velocity distributions were found as the Giotto spacecraft traversed coma Comet Halley. The outer was characterised by interaction between solar wind cometary plasmas; inner outflow neutrals their ionisation products. resultant demands on instrument dynamic had precluded use single sensor for measurements composition. mass spectrometer (IMS) therefore consisted two sensors: one optimised other coma, with each obtaining complementary information in...
For the calibration of comet mass spectrometers a novel system was designed to simulate neutral gaseous atmosphere comets. The facility consists fully automated three-chamber ultra-high vacuum with separate gas mixing unit. molecular beam technique is used for simulation dynamic environment unit allows one produce beams and static environments pure water vapour, mixtures vapour minor constituents also wide range other gases which are expected in uniqueness this lies its emphasis on accuracy...
