In this article we present the first results that we have obtained with a time-of-flight mass spectrometer coupled to a position sensitive detector. This new spectrometer provides a three-dimensional imaging (X and Y positions and time-of-flight) of the ion packet on the detector, with a high acquisition rate and a high resolution on both the mass and the position. This new apparatus is used to measure the electric deflection of PABA (p-amino benzoic acid) and PABA dimer beams and to study the kinetic energy release of the photofragmentation of the PABA dimer.
