Research experience
July. 2018- Postdoc Research
Recently we have started working, along with the nonlinear effects in nonthermal plasma problems, in PIC simulations. For that I visited University of Innsbruck to become familiar with one of the best plasma computational tool namely the Particle in Cell (PIC) that provide an ideal numerical tool for plasma study providing direct simulations of plasma particles. In particular we dealt with the kinetic plasma edge modelling using the electrostatic 1D3V PIC Monte Carlo (MC) code BIT1. This code has been used for studying of general properties of the plasma edge low temperature plasmas, edge plasmas of our day and next generation tokamaks, as well as for teaching of students. Obviously in a short research visit I concentrated on learning the most basic concepts involved in development of BIT1 and get used to it, and to be able to successfully run the code in an MPI environment to reproduce some fundamental plasma physics phenomena, e.g. electrons plasma oscillations in unmagnetized plasmas.The simulation geometry of the code corresponds to a plasma bounded between two conducting walls, diverter plates, and corresponds to the Scrape-off Layer (SOL) of the tokamaks. Different elastic and inelastic processes, such as collisions between charged and neutral particles, different plasma - wall interactions, as well as synthetic diagnostics are implemented into the code. BIT1 uses optimized memory management and allows scaling of massively parallel simulations for at least 8000 cores, allowing simulation of large scale systems with finest resolution.
Dec. 2006-March. 2012 PhD studies Development of an orbit following code based on symplectic integration algorithm (SIA). The developed code is called SIDOC (symplectic integration drift orbit code) and the FORTRAN document is available at Plasma and Energy Physics group, institute for theoretical Physics, Leopold-Franzens University of Innsbruck, Austria Research topic(s): Development of Monte-Carlo orbit following code to calculate fast ions, in particular fusion born alpha particle, trajectories and radial diffusion coefficient in the presence of different magnetic perturbations in tokamak plasma.
