A new photoelectron spectrometer has recently been used to analyze the energy and spatial distribution of
photoelectrons produced by multiphoton ionization of rare gases. It is based on the analysis of the image obtained
by projecting the expanding electron cloud resulting from the ionization process onto a two-dimensional position
sensitive detector by means of a static electric field. In this article, we present the principle of this imaging
spectrometer and the relevant equations of motion of the charged particle in this device, together with an inversion
method that allows us to obtain the energy and angular distribution of the electrons. We present here the inversion
procedure relevant to the case where the electrostatic energy acquired in the static field is large as compared to the
initial kinetic energy of the charged particles. A more general procedure relevant to any regime will be described in a
following article. ©1996 American Institute of Physics.
