In this text, we present the Ion Mobility Spectrometer developed by the Third Research Institute of the Ministry of Public Security. Its radical structure is described, especially the core component, which is called drift tube, is depicted in detail. Also, some questions and corresponding solutions encountered in the research of theinstrument are pointed out, which gives much valuable information to the laterresearchers.

In the second part of this thesis, the physical model, which used to describe the evolution of highly charged ions in the EBIT and provided by Penetrate, are discussed in detail. Based on this model, we have some modifications. The modified physical model takes the effect of the geometry of drift tube, the cumulation of space charge, and ionization heating into account.
