Numerical codes for glow discharge plasma simulations were developed by using Particle in Cell/Monte Carlo Collision (PIC/MCC) method. The model is one-dimensional in coordinate space and three-dimensional in velocity space (1d3v). A modification of Direct Simulation Monte Carlo (DSMC) method known as null-collision method was used for particle collisions. MPI and sub-cycling were used for speed up. The code was validated using benchmarks for capacitively coupled helium discharges and tested with three-dimensional (3d3v) model of electron swarm in argon. Results of the code were compared with the presented results for radio frequency (RF) argon discharge. Code was further used to study effect of electron reflection at the boundaries for RF helium discharge.

Derivation of the parallel PIC/MCC numerical code and its application to the kinetic analysis of photoresonance plasma and the problem of identification of impurities within the PLES method Kuşoğlu Sarıkaya, Cemre; Rafatov, İsmail; Department of Physics (2017) 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) code for numerical simulations of gas discharge plasma was developed. The efficiency of the code was increased by its parallelization using Open MPI. In order to verify the applicability of the code, the benchmark tests were performed under the RF capacitively coupled discharge conditions. The effects of the particle weighting and the Courant number on the computed plasma properties were examined and the convergence of the numerical method with respect t...
Particle in Cell/Monte Carlo Collision Method for Simulation of RF Glow Discharges: Effect of Super Particle Weighting ERDEN, E.; Rafatov, İsmail (Wiley, 2014-08-01) A parallel Particle in Cell/Monte Carlo Collision (PIC/MCC) numerical code for glow discharge plasma simulations is developed and verified. This method is based on simultaneous solution of the Lorentz equations of motion of super particles, coupled with the Poisson's equation for electric field. Collisions between the particles are modelled by the Monte Carlo method. Proper choice of particle weighting is critically important in order to perform adequate and efficient PIC simulations of plasma. Herein, effe...
Measurement of the Isolated Prompt Photon Production Cross Section in pp Collisions at root s=7 TeV Khachatryan, V.; et. al. (2011-02-01) The differential cross section for the inclusive production of isolated prompt photons has been measured as a function of the photon transverse energy E-T(Gamma) in pp collisions at root s 7 TeV using data recorded by the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.9 pb(-1). Photons are required to have a pseudorapidity vertical bar eta(gamma)vertical bar 21 GeV, covering the kinematic region 0.006 < x(T) < 0.086. The measured cross section is found to be in agreem...
Studies of jet mass in dijet and W/Z plus jet events Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-05-01) Invariant mass spectra for jets reconstructed using the anti-k(T) and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 fb(-1), recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV. Leading-order QCD predictions for inclusive dijet and W/Z+jet production combined with parton-shower Monte Carlo models are found to agree overall with the data, and the agreement improves wit...
Implementation of a Monte Carlo method to a two-dimensional particle-in-cell solver using algebraic meshes ŞENGİL, NEVSAN; Tumuklu, Ozgur; Çelenligil, Mehmet Cevdet (2012-01-01) Particle-in-cell (PIC) technique is a widely used computational method in the simulation of low density collisionless plasma flows. In this study, a new two-dimensional (2-D) electrostatic particle-in-cell solver is developed that can be applied to non-rectangular configurations.
