Sub-mm and mm waves are used in many applications such as spectroscopy and imaging, detection of weapons concealed under clothing, detection of diseases and non-destructive product inspection. By developing the THz detection mechanisms, the quality of this usability can be enhanced considerably. The commercial detectors currently used to detect THz waves range from Shottky diodes to bolometers, Golay cells and pyroelectric detectors. However, many of these detectors have limitations in terms of speed and responsivity. In addition, they have a common disadvantage of being expensive. For these reason, glow discharge detectors (GDDs) can be a good alternative since they are cheap and can detect mm-wave or THz radiations without the aforementioned limitations. To obtain optimal detection parameters, one needs to understand the interaction of the radiation with the plasma particles. In the literature, efforts to explain this interaction has focused on qualitative descriptions with analytical models. However, these theories have not been tested with real discharge parameters. For that reason, in this study, the plasma in the GDD is simulated by using previously developed parallel 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) code to obtain the plasma parameters and determine the gas mixture ratios. Initial results show that the discharge current approximates the current measured through the home built glow discharge detector. Using these results an accurate simulation of the GDD discharge parameters has been performed. This platform will allow for understanding the effect of mm sub-mm radiation when added to the simulation which can aid in understanding optimum detection parameters.

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...
Understanding the Effect of THz/mm wave - Plasma Interaction on the Brightness of Glow Discharge Detectors Kusoglu-Sarikaya, Cemre; Akbar, Demiral; Altan, Hakan (2019-01-01) Today, the fact that non-ionizing THz and mm wave can be used in many areas reveals the necessity of devices that can efficiently detect these waves. Compared to existing commercial detectors, cost-effective neon indicator lamps acting as glow discharge detectors (GDDs) are known to be better in speed and responsivity. In GDDs, detection occurs as a result of the interaction between radiation and plasma. Although there are many studies in the literature trying to explain this interaction, these studies are ...
Investigating Glow Discharge Detectors as a Millimeter-Wave/Terahertz Radiation Detection Tool Alasgarzade, N.; Nebioglu, M. A.; Takan, T.; Uzun Kaymak, İlker Ümit; Şahin, Asaf Behzat ; Altan, Hakan (2015-11-05) Compared to other forms of electromagnetic radiation, Terahertz (THz) radiation is considered safe for imaging and detection purposes due to their non-invasive and non-destructive nature. Novel techniques and methods are constantly being evaluated for efficient detection and measurements of THz waves, yet their commercial success is limited due to cost and overall complexity of these systems. Commercially available Glow Discharge Detectors (GDDs) are proven to detect microwave and higher frequency radiation...

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...
