Abstract
Panoramic detector for ions spatially distributed in different beams, wherein it comprises a diaphragm with plane symmetry having an opening permitting the passage of said beams, said diaphragm being brought into a given potential, an accelerating electrode having an opening facing the opening in the diaphragm, said accelerating electrode having a plane symmetry and being brought to a negative potential compared with that of the diaphragm and a plane electrode facing the accelerating electrode and brought to a negative potential compared with that of the diaphragm, the absolute value of the potential of the plane electrode being greater than the absolute value of the potential of the accelerating electrode.
