New GUI of the S AT VAL code

In the paper we present the new version of the SATVAL code for Windows, equipped with the new graphical user interface (GUI). This graphic interface, created using the Power Builder, allows for the easiest preparation and management of data needed for the proper work of the program. The new GUI is addressed to two kinds of users: the advanced ones and the beginners

Computer simulation of the potential distribution inside the plasma chamber of negative ion source

In the paper the computational method and results of simulation of potential distribution inside the plasma region of the negative ion source are presented. The code uses the well known PIC method [1] for the local charge density determination and finite differences method for the Poisson equation [2]. For simplification, the plasma model does not take into account the interaction between the plasma particles. The results of calculations are compared with the experimental data obtained for the RF negative ion source [3]

Parallelization of the Tarticle-in-CelP (PIC) density calculations in plasma computer simulations

The paper deals with the problem of parallelized Particle-In-Cell charge density calculations used in computer plasma simulation. The dependencies between the execution time and the simulation parameters such as the number of 'macro particles', plasma density, particular charge distribution technique and the number of processing units are presented. The local computer cluster and MPI standard have been used in order to parallelize calculations

Application of MPI standard in computer modelling of the ion source plasma

In the paper the adaptation of the TRQR code to run on the massive parallel computer using MPI standard is described. We present the modification of the procedure used for the calculations of the potential spatial inside the plasma chamber of the ion source based on PIC (Particle In Cell) model and the Poisson equation. Parallelisation of the procedure enables us to reduce the CPU time by the factor 6-7 in the case of 8 processor job queue

An MPI-based parallel code for high performance 3-D particle-in-cell ion source plasma simulation

The paper presents parallel version of TRQR code, intended for ion source plasma simulation.The code is written using particle decomposition approach, and enables plasma potential, chargedensity, ion extraction current, etc. calculations. Parallelisation was done using widely acceptedMPI platform. Additionally, the code has been rewritten and optimised in order to achieve betterefficiency. The strong- and soft-scaling properties of the parallel code are shown (tests were doneusing SMP machine), as well as some results of physical meaning. The code in its present formallows calculation involving 5⋅108 pseudo-ions at reasonable wall-clock time (circa 15 hours),which opens the gate for realistic physical conditions plasma calculations

SATVAL - Monte Carlo computer code for windows system

SATVAL is the Monte Carlo computer code which calculates both the final 3D distribution of the ions irradiating the solid target and kinetic phenomena associated with the ion energy loss like sputtering, cascade mixing effect and so on. All atom cascades in the target are followed in detail including the dynamical change of composition of the irradiated sample layers.The code was developed in the Institute of Physics of the Maria Curie-Skłodowska University in Lublin [1-3] and permanently modified for the increase of its calculations possibilities of the phenomena[4-5]
