The construction of a double discharge pulsed electron beam generator and the study of the characteristics of the beam are presented in this paper. The electron beam generator consists of a fast filamentary discharge in superposition with an ordinary glow discharge in low-pressure gases. The filling gas is argon or helium at approximately 0.1 Torr pressure. The duration of the electron beam is shorter than 50 ns and the peak current intensity is of the order of amperes. The electron density is evaluated by making use of Stark broadening of the H-beta line and compared with the full computer simulation method. The pinch effect of the filamentary discharge is evaluated and its size compared with the diameter of the beam.

Electrical, photo-electrical, optical and structural properties of CdSe thin films deposited by thermal and e-beam techniques Hus, S. M.; Parlak, Mehmet (IOP Publishing, 2008-02-07) In this study, electrical, photo-electrical, optical and structural analyses of CdSe thin films deposited by thermal and e-beam evaporation techniques were carried out by measuring temperature dependent conductivity, mobility, photoconductivity under different illumination intensity, photoresponse, transmission and x-ray diffraction. As a result of these measurements, it was observed that the films deposited by the thermal evaporation technique have room temperature conductivity values approximately three o...
Self-consistent model of thermal and ionization non-equilibrium spherical microwave discharge Rafatov, İsmail (IOP Publishing, 2005-07-07) A self-consistent model of a spherical microwave discharge is presented. The model takes into account thermal and ionization non-equilibrium of the discharge plasma. We adopt a partial local thermodynamic equilibrium model for the plasma in two-temperature approximation. Numerical experiments are carried out for the discharge in argon at atmospheric pressure. Results are presented for the characteristics of the discharge plasma against the external parameters (the power and frequency of the applied electrom...
Spatial stabilization of Townsend and glow discharges with a semiconducting cathode Salamov, BG; Ellialtioglu, S; Akınoğlu, Bülent Gültekin; Lebedeva, NN; Patriskii, LG (IOP Publishing, 1996-03-14) The physical processes determining the functions of an ionization system and especially the discharge stabilization by the distributed resistance of a semiconducting cathode in such a system are studied. The current-voltage (I-U) characteristics of the system with a semiconducting GaAs cathode are obtained experimentally as functions of the gap pressure P (16-760 Torr) and inter-electrode distance d (10 mu m to 5 mm), which are varied for the first time over very wide ranges. The experiments showed that the...
Self-consistent model of non-equilibrium spherical microwave discharge Rafatov, İsmail (IOP Publishing, 2004-10-21) A self-consistent model of a non-equilibrium spherical microwave discharge is presented. We use a two-temperature plasma model. Numerical experiments are carried out for the discharge in argon at atmospheric pressure. Results are presented for the characteristics of the discharge plasma against the external parameters (the power and frequency of the applied electromagnetic field and the size of the discharge chamber).
Electrical and photoelectrical properties of Ag-In-Se thin films evaporated by e-beam technique ÇOLAKOĞLU, Tahir; Parlak, Mehmet (IOP Publishing, 2009-02-07) In this study, the electrical and photoelectrical properties of the Ag-In-Se thin films deposited by the e-beam technique have been investigated by carrying out temperature dependent conductivity, photoconductivity under different illumination intensities and photoresponse measurements between 380 and 1050 nm, as a function of annealing temperature. The measured conductivity values of the films at room temperature depending on the annealing temperatures vary in the range 1.9 x 10(-6)-5.2 Omega(-1) cm(-1). A...
