Transmission of terahertz pulses through DC glow discharge plasma was investigated for different gases. The pressure was kept in between the range of 0.1 torr–0.5 torr and for each pressure different measurements were taken at 5 mA, 10 mA and 15 mA plasma currents. Moreover, emission spectrum of Air, N2 and Ar plasma analysis were done respectively. It was found that the transmission of terahertz pulses through nitrogen plasma was considerably affected compared to that of the argon plasma.

Characterization of Air-Nitrogen-Argon DC Glow Discharge Plasma with THz Time Domain Spectroscopy Cinar, K.; Karaoglan, G.; Tosun, Z.; Akbar, D.; Altan, Hakan (2009-11-06) Transmission of terahertz pulses through DC glow discharge plasma was investigated for different gases. The pressure was kept in between the range of 0.1 torr-0.5 ton and for each pressure different measurements were taken at 5 mA, 10 mA and 15 mA plasma currents. Moreover, emission spectrum of Air, N(2) and Ar plasma analysis were done respectively. It was found that the transmission of terahertz pulses through nitrogen plasma was considerably affected compared to that of the argon plasma.
The interaction of terahertz pulses with dc glow discharge plasma Tosun, Z.; Akbar, D.; Altan, Hakan (2009-09-25) Transmission of terahertz pulses in DC glow discharge plasma was investigated. Experiments were performed at various discharge currents and moderate pressures. The analysis of the experimental results shows that the transmission of the terahertz pulses through the plasma is dependent on the polarization of the wave with respect to the electric field within the plasma. As a result the transmission decreases as the pressure decreases for p-polarization (perpendicular to the plasma DC electric field). However,...
Observed nonlinearities in a DC semiconductor-gas discharge system ÇAYLI, YAVUZ KERİM; MANSUROĞLU, DOĞAN; Uzun Kaymak, İlker Ümit (Canadian Science Publishing, 2018-07-01) Nonlinear behaviour of a direct current (DC) driven semiconductor-gas discharge plasma is investigated experimentally. The setup consists of two planar electrodes separated by a gap of 1 mm. Plasma glow is generated between a semiconductor cathode and a transparent anode using nitrogen gas at partial atmospheric pressure. Nonlinear behavior of the discharge is investigated by varying the applied DC voltage while monitoring the plasma current (I), voltage (V), and the optical emission, (i.e., amplified volta...
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...
Investigation of dc generated plasmas using terahertz time domain spectroscopy Karaoğlan, Gülten; Altan, Hakan; Department of Physics (2010) This thesis is on the topic of investigation of the characteristics of DC Glow Discharge plasmas. Emphasis is given on characterizing the plasma electron density. The methods of generating and detecting THz pulses are described. THz transmission spectroscopy and plasma emission spectroscopy is examined. Transmission spectrum is taken for Air, gaseous Nitrogen and Argon plasmas. Moreover, emission spectrum of Air, N2 and Ar plasma analysis were done respectively. It was found that the transmission of teraher...
