Recently, there has been much interest in the capability of low cost glow discharge detectors (GDDs) for detection of terahertz radiation. To utilize them in applications such as terahertz 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 examine the interaction mechanism of GDDs with terahertz radiation using terahertz time domain spectroscopy in a broader range of frequencies between 0.05 and 0.5 THz. Our results show that in addition to terahertz-induced oscillations in the plasma charge density, the structure of the GDD itself plays an important role in the detection mechanism. We observe that by increasing the bias voltage on the gap, not only can we greatly reduce the transmission at a specific frequency, but we can also tune it as well, suggesting that these devices can be used as hybrid plasma filters.

An optical fiber radiation sensor for remote detection of radiological materials Klein, DM; Yukihara, EG; Bulur, Enver; Durham, JS; Akselrod, MS; McKeever, SWS (Institute of Electrical and Electronics Engineers (IEEE), 2005-08-01) This paper demonstrates the feasibility of a portable radiation sensor system that uses the pulsed optically stimulated luminescence technique to remotely interrogate an aluminum oxide (Al2O3:C) radiation sensor via an optical fiber. The objective is to develop a system for applications requiring simple and inexpensive sensors for widespread monitoring of ionizing radiation levels, which can be remotely interrogated at regular periods with little or no human intervention and are easy to install, operate, an...
Characterization of a Glow Discharge Detector with Terahertz Time Domain Spectroscopy 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...
Ultra-High Precision Radiation Dosimetry via Laser Bleaching the Color Centers in Fast Recovery Optical Fiber Sensors Ghahrizjani, Reza Taheri; Ameri, Mohsen; Jahanbakhsh, Hossein; Sadeghi, Hossein; Mohajerani, Ezeddin (Institute of Electrical and Electronics Engineers (IEEE), 2020-06-01) High energy electromagnetic radiation or heavy charged particles are extensively used for medical treatment of certain cancers. Precise prediction or measurements of energy deposition of any types of radiation on tissue is critical in radiation therapy. In this research, the sensitivity of optical fiber dosimeters specifically doped with phosphor (P), Germanium (Ge) and Erbium (Er) are analyzed using Co-60 source at 169 cGy/min. The sensors are calibrated and the values of radiation induced attenuation (RIA...
Label-Free DNA Detection Using a Charge Sensitive CMOS Microarray Sensor Chip Musayev, Javid; Adlguzel, Yekbun; KÜLAH, HALUK; Eminoglu, Selim; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-01) This paper presents label-free DNA detection using a charge sensitive microarray sensor. The microarray sensor, fabricated with a standard CMOS process, contains 1024 detector elements integrated together with their readout circuit in a single chip. This microarray sensor chip is developed for biosensing applications involving label-free detection of charged particles and molecules with improved sensitivity. The proposed chip is used for the detection of DNA immobilization and hybridization by directly sens...
A Dual-Resonator Temperature Sensing Approach With Time Base Error Suppression Kaya, Onurcan; Azgın, Kıvanç (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-15) In this study we present a novel dual-resonator temperature sensor which can be embedded in other MEMS sensors for improved thermal compensation and on-the-run calibration. For accurate temperature measurements, the proposed method mitigates time base errors in frequency counting, eliminates the need for a highly accurate reference clock and can cancel out the effects of aging of the time base without using a calibration process. The sensor structure is composed of a strain amplifying beam and two Double En...
