Design of 3mm Band Detector Indoor Calibration System
نویسندگان
چکیده
A 3mm band detector indoor calibration system is introduced in this paper, which is based on a STM32 embedded system. This embedded control system includes noise source control circuit, database circuit, a real time clock circuit, humidity and temperature sensor circuit, PS/2 interface circuit and SD card interface circuit. And a database, which contains radiation characteristics of metal targets, is built in this calibration system. Experiment results demonstrate that the indoor system could satisfy the requirement of 3 mm band detector calibration.

Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields
In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
متن کاملRefractive Dual Band Infrared Imager Optical Design
Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...
متن کاملA Personal, Distributed Exposimeter: Procedure for Design, Calibration, Validation, and Application
This paper describes, for the first time, the procedure for the full design, calibration, uncertainty analysis, and practical application of a personal, distributed exposimeter (PDE) for the detection of personal exposure in the Global System for Mobile Communications (GSM) downlink (DL) band around 900 MHz (GSM 900 DL). The PDE is a sensor that consists of several body-worn antennas. The on-bo...
متن کاملSuperconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector
A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...
متن کاملDesign Considerations for a GBT 68-92 GHz Receiver
Scientific motivation for equipping the GBT with receivers for the 3mm band (68-116 GHz) has been discussed in several memos [1]-[3], and later presented in a proposal by the GBT 3mm Receiver Working Group [4]. It was decided that the first receiver module to be built should be capable of both continuum detection and spectroscopy in the 68-92 GHz band (Module 1). Other frequencies and capabilit...
