Commercially available neon indicator lamps (also known as Glow Discharge Detectors) are low-cost, sensitive detectors operating at room temperature for mm-wave/Terahertz detection. Furthermore, their high speed operation make them attractive from the stand-point of applications in the far-infrared region of the spectrum, however questions still remain regarding the mechanisms involved in the detection of this type of radiation. In order to study the plasmas generated in these lamps, a DC gas discharge chamber is designed and built. Glow discharge generated using an inert gasis investigated in terms of its far infrared transmission. Keeping the anode-cathode separation constant the transmitted signals are found to be independent of the pressure and applied bias for a pure Neon plasma.

The Effect of Phosphor Coating on THz/mm wave-Plasma Interaction in Glow Discharge Detector
Kuşoğlu Sarıkaya, Cemre; AKBAR, DEMİRAL; Altan, Hakan (2019-10-21)
Glow discharge detectors (GDDs) attract attention because they have advantageous features compared to commercial detectors currently used for detecting THz and mm waves. Studies in the literature show that N523-coded GDD which has a phosphor coating exhibits the best performance as a detector. However, to the best of our knowledge, no study has been carried out yet to demonstrate the effect of phosphor coating on the detection mechanism. Therefore, in this study, it is aimed to understand this effect by sim...
Micro processing by intense fast electron beam
Goktas, H; Kirkici, H; Oke, G; Udrea, M (2001-06-22)
Generation of intense electron beams by superposing two discharges, namely a low pressure do glow discharge and a high current pulsed discharge at pressures and voltages very similar to that of the pseudo-spark gap devices, has been reported previously [1, 2]. The small diameter, high peak current and short pulse length are the characteristics of the electron beam generated using this technique. In this technique, no high vacuum facilities are necessary, and many applications such as micro processing, X-ray...
Parallel 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) Simulation of a Glow Discharge Millimeter Wave Detector
Kuşoğlu Sarıkaya, Cemre; Akbar, Demiral; Altan, Hakan (2018-01-15)
Glow discharge detectors can be a good alternative to existing Schottky diodes, Golay cells and pyroelectric detectors because they are inexpensive and can detect mm-wave and sub-mm radiation successfully. This detection occurs as a result of the interaction of the radiation with the electrons in the plasma. It is required to understand this interaction mechanism to obtain optimum detection parameters. Previous methods have focused on understanding the interaction using analytical models, where the radiatio...
Glow discharge detectors (GDDS) for millimeter-wave radiation detection and imaging
Alasgarzade, Namig; Uzun Kaymak, İlker Ümit; Department of Physics (2018)
Commercially available indicator lamps, also known as Glow Discharge Detectors (GDDs), are employed for the purpose of millimeter wave radiation detection and imaging. Previous studies show that dominant radiation detection mechanism for GDDs is enhanced cascade ionization. The current-voltage characteristics of GDDs are obtained and working mode is found as abnormal glow mode. The plasma parameters such as electron temperature and gas composition inside GDDs are studied using Optical Emission Spectroscopy ...
Detection of far-infrared radiation using glow discharge detectors
Takan, TAYLAN; ALASGARZADE, Namig; Uzun Kaymak, İlker Ümit; Sahin, Asaf B.; Altan, Hakan (2016-05-01)
The plasma medium, created inside the neon indicator lamp, enables the detection of a wide wavelength range of differential or modulated EM signals. The interaction between the plasma and various frequency EM waves are still being investigated and in the mm-wave/terahertz range the interaction mechanism is still not well understood. In this study commercially available neon indicator lamps are studied using both time-domain and continuous wave mm-wave/THz measurement systems. The glow discharge detector res...
