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 simulating the interaction between the plasma consisting of Ne-Xe mixture in N523 coded GDD and THz/mm waves with the parallel 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) code.

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 cham...

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 ...

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...

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 re...

Cinar, Kamil; Altan, Hakan; ŞAHİN, ASAF BEHZAT (2013-09-06)
The capability of low cost glow discharge detectors (GDDs) for detection of terahertz (THz) radiation draws attention recently. In order to employ them in applications such as THz imaging these studies have typically focused on the response of the GDD at specific frequencies. To better understand the spectral behavior of glow discharges, we have not only examined the response of the GDD at a specific frequency of 118 GHz, but also we examined the interaction mechanism of GDDs with THz radiation using terahe...
