Abstract
A mass spectrometry apparatus includes means to irradiate a specimen with a beam of radiation to desorb ions for mass analysis. The apparatus comprises means for deflecting and scanning the beam and attenuator means arranged to vary the attenuation of the beam such that the attenuation is a function of the beam position in the scan.
