Proposal for Electron Beam Induced Remote Sensing X-Ray Fluorescence Investigation of Minor Bodies in the Solar System. Experiment IND-X

摘要

The composition of the surface material of minor bodies in the solar system can be measured using a semiconductor soft x-ray spectrometer mounted on the space probe. The characteristic x-rays are excited by a 20 kV low current electron beam of a space-born electron gun. After the description of the main features of the technique, estimations on its sensitivity, supported by a model experiment, are given. The minimum fly-by distance to apply this method can be estimated as a few kilometers. (Atomindex citation 15:048020)
