Anna Efimova2020-09-16 15:57 Good morning! What number of particles do you use?
Marina Boronina2020-09-16 15:57 Hello, Anna. In these computations we used 4 background particles per cell (total 4800) and every time unit 200 particles were injected (8000 at t=40 and 32000 at t=160).
Anna Efimova2020-09-16 15:57 Thank you!
V.T. Astrelin2020-09-16 15:57 Good evening, Marina! p.3 - In your model ions are injected into plasma. Does the plasma potential change due to addition space charge from ions?
Marina Boronina2020-09-16 15:57 Good evening, Vitaly Timofeevich. No, it doesn't, since we don't add only ions, we add electrons as well.
V.T. Astrelin2020-09-16 15:57 Sorry, no problem - see last equation in p.5
Marina Boronina2020-09-16 15:57 Yes, you are right.
Dmitry Shmelev2020-09-21 14:59 Could you explain what the following phrase means: “To solve the Vlasov equations by the PIC method, a transition to Cartesian coordinates and back to cylindrical coordinates is used.” Or maybe you could give a reference where I could read about it in more detail?
Marina Boronina2020-09-21 14:59 Dmitry, the algorithm is proposed by J. Boris in Boris J 1970 Proc. Fourth Conference on Numerical Simulations of Plasmas, Washington D.C., USA, pages 3-67.
