Abstract : An energy compensator of the Poschenrieder type for an atom probe field ion microscope is described. The compensator has a large acceptance angle, 0.1 radians. The mass resolution has been measured for different ion entrance angles and energy deficits, and is compared to the mass resolution calculated from the focusing errors of the compensator.
