Ion-optical characteristics of a laser mass spectrometer with a coordinate-sensitive microelectronic detector

The ion-optical systems of a mass spectrometer with a laser ion source and coordinate-sensitive microelectronic detector are analyzed using the matrizant method. The dispersion properties of the mass spectrometer, as well as ion beam radial and axial focusings in its optimized ion-optical system, are determined, and first-and second-order angular and velocity aberrations of the image are corrected. The basic parameters and characteristics of a refined (according to calculation results) version of the laser mass spectrometer with a coordinate-sensitive microelectronic detector are presented.
