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 radiation is generally thought to increase the collision frequency of electrons in the plasma, however these theories were not tested against real discharge parameters. For that reason, in this study, the plasma formed inside the detector is simulated by using parallel 1d3v PIC/MCC code, which was previously developed (Kusoglu-Sarikaya et al., 2016) to better understand how the glow discharge forms under different pressure and gas concentrations. The effectiveness of the simulation is compared with mm-wave experiments performed on both commercially obtained and home-built glow discharge detectors. Initial results show that the 1d3v PIC/MCC code can simulate the discharge parameters that are observed in the measurements. Using this platform future studies will focus on understanding the effect of the sub-THz radiation on the collision frequency and observed parameters of the discharge.

THz transmission and detection through glow discharge detectors
Cinar, K.; Altan, Hakan; Sahin, A. B. (2013-04-30)
The capability of low cost glow discharge detectors (GDDs) to detect terahertz (THz) radiation has drawn much 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 tera...

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...

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...
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...
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 ...
