Reported electron collision cross sections data in the energy range ~ 0 to 300 eV from gaseous biomolecule Tetrahydrofuran (THF) have been used calculate distribution function (EEDF) and swarm parameters for electrically excited of THF, using a two-term solution Boltzmann equation. The namely (mean energy, drift velocity, diffusion coefficient, mobility, characteristic attachment ionization coe...

We used helical antenna-coupled radio frequency (RF) plasmas to study the evolution of mode transition power and electron kinetics under different applied magnetic fields argon pressures. Langmuir probe emission spectrum data indicate that discharge changes from capacitive coupling E inductive H through a strong mixed (E + H). One reason for this strongly ionization is antenna structure, which ...

In a laser-irradiated plasma, the Langdon effect makes electron energy distribution function (EEDF) tend to super-Gaussian distribution, which has important influences on laser plasma instabilities. this work, of EEDF convective stimulated backward Raman scattering (SRS) and Brillouin (SBS) are studied systematically for wide range typical parameters in inertial confinement fusion (ICF). Distin...

The use of a Langmuir probe system in two GEC cells is reviewed. The major problems associated with probe diagnostics in a GEC cell are outlined and discussed. While the data base is still insufficient to give definitive values for many parameters, a number of standard measurements are put forward. The plasma density in argon is 9×109 cm-3 (±20 %) at an applied rf voltage of 250 V (500 V peak t...

Coaxial Hall discharges (also known as Hall thrusters, stationary plasma thrusters, and closed-drift accelerators) are cross-field plasma sources under development for space propulsion applications. The importance of the electron-wall interaction to the Hall discharge operation is studied the through analysis of experimental data and simulation of the electron energy distribution function (EEDF...

Trochoidal electron monochromator (TEM) which uses crossed homogeneous electric and magnetic fields has been investigated in a numerical simulation using the SIMION 8.0 package. The electron trajectory calculations have been carried out for large number of initial electrons with finite energy spread and angular distribution function. The electron energy distribution function (EEDF) of the TEM h...

A mono-dimensional code for the simulation of effects High Frequency Ignition systems (HFI) on production chemical radicals was developed and here presented. The simulations were carried out by considering typical environmental thermodynamic conditions a nowadays engine at full load. An electron transport model is linked with Boltzmann solver coupled chemistry solver, affecting Electron Energy ...

The relaxation of the electron energy distribution function (EEDF) in the post-discharge of an omega/(2pi)=2.45 GHz microwave discharge in N2 has been investigated by solving the time-dependent Boltzmann equation, including a term taking into account electron losses by diffusion under the presence of a space-charge field. It is shown that although the high-energy tail of the EEDF is rapidly dep...

Abstract In order to obtain creditable data an applicable method to optimize parameters of the Langmuir probes and circuits in a stationary laboratory device is investigated and an experimental criterion of the probe dimension is developed. To obtain the electron temperature and density the Electron Energy Distribution Function (EEDF) approach with less computing time and more accurate results ...
