Miroslav Horky of the Czech Technical University will talk about:
PIC simulations of instabilities in weakly collisional plasmas
I will talk about research done during my stay at the University of Oslo in the last year. We simulated plasma instabilities in weakly collisional plasmas under the presence of E x B fields. Both, electrons and ions were magnetized in our simulations and we changed only the type of ion-neutral collisions. For these different ion-neutral collision types we found different electron heating rates and other instability characteristics, such as electrostatic potential fluctuations and electrostatic wave spectra. At first I will present theoretical background of our research, then our results and in the end I would like to introduce current analytical study of the simulated instabilities.
