Abstract

A high voltage particle accelerator and an energy analyzer fed back to the accelerator, in which the beam of extremely small diameter from a particle source of the field-emission or field-ionization type and the energy analyzer function to produce precisely defined high voltages; use of such an accelerator and focusing lenses to produce a microbeam with reduced chromatic aberration; and production of a microbeam by use of such an accelerator and focusing lenses of the achromatic quadrupole type, further compensated for aperture aberration.
