Experimental activity and numerical simulations for the plasma experiment of the ESA CLUSTER Project

The ESA CLUSTER project consists of a cluster of four space-crafts which, when orbiting close to one another, will allow a detailed study of the terrestrial magnetosphere and of its interaction with the solar wind. IFSI actively participates in this project with the conceptual design and mechanics of the hot ion analyser for the Cluster Ion Spectrometer experiment (CIS). This analyzer is of the «top-hat» type and provides the three-dimensional distribution function of ions in the (0÷40) keV range every two seconds. Within this project, the experimental activity of the group consisted in setting up a vacuum chamber with ion source, mass spectrometer and two azimuthal and polar rotating platforms, in dedicating a computer to data acquisition and monitoring of the physical parameters such as pressure inside the chamber and, finally, in the construction of a prototype of the sensor. The theoretical activity, preliminary to the design of the sensor, is based on the numerical simulation of the sensor in various geometries. It is the aim of the present study to compare between the experimental and theoretical response of the sensor for two different configurations.
