Good morning! What number of particles do you use?

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).

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?

Good evening, Vitaly Timofeevich.
No, it doesn't, since we don't add only ions, we add electrons as well.

Sorry, no problem - see last equation in p.5

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?

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.
In Russian you may find it in Березин Ю.А., Вшивков В.А. Метод частиц в динамике разреженной плазмы. Новосибирск: Наука, 1980, p. 39.
Or, in English in our paper https://iopscience.iop.org/article/10.1088/1742-6596/1336/1/012017/pdf
