Project Description
The Khalizov group at New Jersey Institute of Technology studies chemical and physical processes that transform environmental pollutants, such as atmospheric mercury and aerosol nanoparticles (https://centers.njit.edu/krg/). Research activities involve experimentation and modeling, and the group has been providing opportunities for undergraduate and graduate projects not only in experimental, but also in computational fields. Available projects range from using existing software packages for building and testing models of various physical processes to the development and optimization of new algorithms and program codes.
THIS PROJECT: Use an ion optics simulation program SIMION to build a model of the mass spectrometer ion drift tube, calculate electric field, evaluate ion trajectories, and then optimize the design of the drift tube to improve ion transmission and focusing [Zheng et al., 2010; Zheng et al., 2015; Khalizov et al., 2020].
