Simulationof a Bayard-Alpert ionization gauge with the PIC code Warp

Sammanfattning: At RISE Research Institutes of Sweden, there is an interest in computer simulations of the physics related to ionization gauges. The objective of this thesis is to find out if the open source code Warp can be used for simulating the physics of interest. In this thesis it is explained what an ionization gauge is and the physics and the governing mathematical equations of the simulations are described. How those governing equations are solved and the algorithms used in Warp is also discussed in this thesis. The results of the simulations are presented in the thesis and a discussion of which parts of Warp that need to be further developed to successfully simulate the physics is carried through.
