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 helium, argon or nitrogen at approximately 0.1 Torr pressure. The duration of the electron beam is shorter than 30 ns and the peak current intensity is typically 20 A. The deposition of carbon on a substrate has been done by two methods; firstly, the low pressure argon gas was replaced by methane gas as a plasma source and, secondly, a graphite target was used. The high intensity electron beam evaporates at every shot a small amount of the material that is collected by different substrates. Both methods lead to thin layer carbon deposition on the substrates that were analyzed by using Scanning Electron Microscope (SEM).

Synthesis of carbon nanotubes by a plasma based pulsed electron beam generator Goktas, H.; Ayhan, U. B.; Gündüz, Güngör; Disbudak, H.; Eryilmaz, E.; Oke, G.; Cicek, B.; Somer, M. (IOP Publishing, 2006-01-01) Carbon nanotubes (CNTs) were synthesized by using a plasma based electron beam generator, which has a fast filamentary discharge formed from the superposition of an ordinary low-pressure dc glow and a high-current pulsed discharge. To our knowledge, CNTs are synthesized for the first time by this method. Acetylene was used as the carbon source and the iron catalyst coated silica substrates were prepared by the sol-gel technique. The silica plates were first coated with an appropriate iron (III) nitrate solu...
Design and implementation of a low emittance high power thermionic DC electron gun Sezer, Mustafa; Güler, Ali Murat; Department of Physics (2021-2-8) In this thesis, a thermionic electron gun generating low emittance and the high power electron beam is designed. The thermionic cathode made of a LaB6 single crystal is chosen as a thermionic emitter because of its properties ensuring high electron beam current in lower temperatures which provide lower emittance. The main goal of the gun design is to achieve a high DC beam current and low emittance. Computer Sim- ulation Technology (CST) and MATLAB are used to design the gun and optimize electrode shapes an...
Fast Double Probe Technique And Effect of Non-Uniform Glow Discharge System on Plasma Parameters Akbar, D.; Bilikmen, S. (2005-09-02) The non-uniform dc glow discharge plasma system is studied by using isolated computer controlled three couples of double probe system (TCDP)in argon gas, simultaneously. The double probe is more applicable than the single probe in diagnostics, specially in plasma reactors which have insulating or semi-insulating walls. TCDP technique has been developed to use for magnetized, un-magnetized, and for low oscillating plasma systems by using optically isolated circuitry to minimize the measurement errors with hi...
BACKGROUND SUPPRESSION OF AR LINES IN GLOW-DISCHARGE ATOMIC EMISSION-SPECTROMETRY BY A LOCK-IN AMPLIFIER AND KALMAN FILTER DECONVOLUTION ULGEN, A; DOGAN, M; Gökmen, Ali; YALCIN, S (1993-01-01) The Ar spectral lines are suppressed in Grimm-type glow discharge lamp atomic emission spectrometry (GDL-AES) by a double voltage modulation technique. The GDL is modulated between two voltage levels, typically 400 and 700 V. At the lower voltage level mainly Ar emission contributes whereas at the higher voltage level both Ar and atoms sputtered from the cathode contribute to the emission. The Ar emission spectrum at the lower voltage level is multiplied by a constant factor to scale it up to the same level...
Modelling of non-uniform DC driven glow discharge in argon gas Rafatov, İsmail; BILIKMEN, S. (Elsevier BV, 2007-07-16) Physical properties of non-uniform DC-driven glow discharge in argon at pressure 1 torr are analyzed numerically. Spatially two-dimensional axial-symmetric model is based on the diffusion-drift theory of gas discharge. Results presented compare favorably with the classic theory of glow discharges and exhibit good agreement with the experimental result. Comparison with the result of spatially one-dimensional model is performed. (c) 2007 Elsevier B.V. All fights reserved.
