We developed 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) numerical code for the RF (radio-frequency) capacitive glow discharge. This method includes the solution of the Lorentz force equation for the motion of super particles and the Poisson equation for the electric field. Collisions between the particles are modeled with the Monte Carlo method. In this process, the isotropic and charge exchange collisions between the ion-neutral pairs, as well as the elastic, excitation and ionization collisions between the electron-neutral pairs are taken into account. Test calculations were carried out and numerical code was validated by comparison with the published simulation results.

Simulations on glow discharge: development and validation of one-dimensional kinetic model by particle in cell/monte carlo collision method
Tiryaki, Özgecan; Çakır, Serhat; Department of Physics (2019)
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-dime...
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...
Experimental characterization of collapse-mode CMUT operation
Oralkan, Omer; Bayram, Barış; Yaralioglu, Goksen G.; Ergun, A. Sanli; Kupnik, Mario; Yeh, David T.; Wygant, Ira O.; Khuri-Yakub, Butrus T. (2006-08-01)
This paper reports on the experimental characterization of collapse-mode operation of capacitive micromachined ultrasonic transducers (CMUTs). CMUTs are conventionally operated by applying a direct current (DC) bias voltage less than the collapse voltage of the membrane, so that the membrane is deflected toward the bottom electrode. In the conventional regime, there is no contact between the membrane and the substrate; the maximum alternating current (AC) displacement occurs at the center of the membrane. I...
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...
Evaluation of mechanical properties of Bi12SiO20 sillenite using first principles and nanoindentation
Isik, M.; Sürücü, Gökhan; Gencer, A.; Hasanlı, Nızamı (2021-08-01)
The mechanical and anisotropic elastic properties of Bi12SiO20 (BSO) were investigated using density functional theory (DFT) calculations and nanoindentation. The calculated and experimentally observed XRD patterns of the compound were reported and the crystal structure of the BSO was determined to be cubic with the lattice constant of a = 1.025 nm. The second-order elastic constants and related polycrystalline elastic moduli (e.g. shear modulus, Young's modulus, Poisson's ratio, linear compressibility and ...
