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. Although, the plasma generated inside the GDDs enables the detection of the EM radiation, the interaction mechanism is not fully understood. In this study, we investigate various types of GDDs that are commercially available, and characterize their overall behaviour in response to both CW and modulated EM radiation. In addition, the response from various GDDs to the mm-wave/THz radiation are surveyed for the range of 260–380 GHz. Measurements show that response signal at certain frequencies within the range are attenuated suggesting a resonance frequency possibly based on the electrode structure.

Monitoring radiation induced alterations in biological systems, from molecules to tissues, through infrared spectroscopy Demir, Pinar; Severcan, Feride (2016-01-01) Humans can be exposed to non-ionizing and ionizing radiation for diagnostic, therapeutic, accidental, and occupational reasons. Consequently, the effect of radiation on biological systems has attracted the attention of researchers for a rather long time. This review is about the mid-infrared Fourier Transform Infrared (FTIR) spectroscopic characterization of non-ionizing and ionizing radiation-induced changes in DNA, lipids, and proteins, as isolated or synthetic macromolecules, and in biological membranes,...
Understanding the detection mechanism of mm-wave radiation in glow discharge detectors Sarikaya, Cemre Kusoglu; Akbar, Demiral; Ribeiro, Marco A.; Altan, Hakan (2018-09-11) 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...
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...
Space radiation environment and radiation hardness assurance tests of electronic components to be used in space missions Amutkan, Özge; Esendemir, Akif; Department of Physics (2010) Space radiation is significantly harmful to electronic Components. The operating time, duration and orbit of the space mission are affected by the characteristic of the radiation environment. The aging and the performance of the electronic components are modified by radiation. The performance of the space systems such as electronic units, sensors, power and power subsystem units, batteries, payload equipments, communication units, remote sensing instruments, data handling units, externally located units, an...
