The Giotto Ion Mass Spectrometer.
Abstract
The Giotto Ion Mass Spectrometer (IMS) consists of two sensors: one optimised for the outer and the other for the inner coma of Halley's comet. Both sensors feature mass imaging characteristics, thereby permitting simultaneous measurements of several ion species by means of multi-detector arrays. Resultant mass-per-charge resolution is ≥20. In addition to mass per charge, the energy per charge, the elevation and azimuth of incident ions are measured.
