Application of the Direct Simulation Monte Carlo Method to Mass Spectrometer Flow.

Abstract

Technical progress is described in the development of a Monte Carlo code to simulate the flow within a mass spectrometer used to sample stratospheric ion clusters. A procedure is presented for spatially segmenting the solution region and a new formulation of the molecular internal energy model is described in terms of a Chi-Square distribution function. The modeling of accelerations due to electric fields is discussed and a comparison with published data for diffusive species species separation is made. (Author)
