Simulering av en Bayard-Alpert joniserende tryckgivaremed hjälp av PIC-koden Warp (Swedish)
Abstract [en]

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.  

Abstract [sv]

RISE Research Institutes of Sweden, är man intresserad av att göra datorsimuleringar av fysiken bakom joniserande tryckgivare. Målet med denna uppsats är att ta reda på om det är möjligt att använda den öppna källkoden Warp för att genomföra simuleringar av fysiken som man är intresserad av.

I den här uppsatsen förklaras det vad en joniserande tryckgivare är och fysiken och de styrande matematiska ekvationerna bakom simuleringarna beskrivs. Hur dessa styrande ekvationer löses och algoritmerna som används i Warp diskuteras också i denna uppsats.

Resultaten från simuleringarna presenteras i uppsatsen och det förs en diskussion om vilka delar utav Warp som behöver vidareutvecklas för att framgångsrikt kunna simulera fysiken.
