Ways of Developing Analyzers for Static Mass Spectrometers

Resumo

A prism mass spectrometer with triple focusing of the ion beam using a cone-shaped achromatic prism (CSAP) is considered. The CSAP has a record high angular mass dispersion of approximately 50 rad upon 100% variation of the mass. The performance of a prism mass analyzer with collimating and focusing transaxial lenses is simulated using the Monte Carlo method. The resolution and the quality parameters of such a mass analyzer are shown to exceed those of existing static devices by several times. A resolving power of several million can be obtained using narrow beams on a small device with sub-meter dimensions.
