摘要
This probe, intended to be placed in a uniform magnetic field, comprises an ion acceleration zone, a circular sector (6) which is polarised (biased) to create an accelerating electric field in the zone, an ion collector (8), a conductive grid (36) at the entry of the zone, for fixing the potential at this entry, the distance between this grid and the sector being sufficient for the ions to drift in the zone from their incidence position onto the grid. The sector has an entry slit (38) which is offset with respect to this incidence position so that the electric field is uniform in the acceleration zone. IMAGE
