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, and maintain. Results on the optimization and performance of the system are presented. The current minimum detectable dose is of the order of 5 mu Gy, which is already satisfactory for applications such as the monitoring of radioactive plumes from radioactive waste sites. We also discuss potential developments that could decrease the minimum detectable dose to allow radiation doses as low as the background level to be measured over short time intervals, making the system more versatile for detecting radiological materials.

Characterization of a Glow Discharge Detector With Terahertz Time Domain Spectroscopy Cinar, Kamil; Bozaci, Hasan Mert; Altan, Hakan (Institute of Electrical and Electronics Engineers (IEEE), 2013-07-01) 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...
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...
A low-cost uncooled infrared microbolometer detector in standard CMOS technology Tezcan, DS; Eminoglu, S; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2003-02-01) This paper reports the development of a low-cost uncooled infrared microbolometer detector using a commercial 0.8 mum CMOS process, where the CMOS n-well layer is used as the infrared sensitive material. The n-well is suspended by front-end bulk-micromachining of the fabricated CMOS dies using electrochemical etch-stop technique in TMAH. Since this approach does not require any lithography or infrared sensitive material deposition after CMOS fabrication, the detector cost is almost equal to the CMOS chip co...
An Adaptable Interface Circuit With Multistage Energy Extraction for Low-Power Piezoelectric Energy Harvesting MEMS Chamanian, Salar; Ulusan, Hasan; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-03-01) This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy. The circuit is optimized to operate...
All 3-D Printed Free-Space Setup for Microwave Dielectric Characterization of Materials Hajisaeid, Ehsan; Dericioğlu, Arcan Fehmi; Akyurtlu, Alkim (Institute of Electrical and Electronics Engineers (IEEE), 2018-08-01) In this paper, the development of an all 3-D printed wide band (2-18 GHz) free-space measurement system for characterizing the complex dielectric properties of flexible as well as rigid materials was demonstrated. Each part of the setup was designed and simulated precisely to show the effect of the 3-D printed quasi-optical lenses placed in front of the wide band ridged horn antennas on the beam and radiation pattern. More than 10 parts of the setup were 3-D printed using two different 3-D printers, and the...
