چکیده

An X-ray pulsar is a remnant of massive star evolution, collapse, and supernova explosions. It has an extremely stable spin cycle known as the most accurate astronomical clock in natural world. presents high-precision navigational information, such location, speed, time, attitude, which are used deep space exploration interstellar flight, navigation (XPNAV). However, energy from very low its signal weak; this soft X-ray. In medium radiation spectroscopy, semiconductor detectors, especially silicon drift detectors (SDD), achieve best resolution. study, 314 mm 2 600 double-sided spiral hexagonal detector (DSSH-SDD) single cell for detection analyzed based on ultra-pure high-resistance silicon. The DSSH-SDD device fabricated using high-resistivity substrates patterned with ion-implanted electrodes. This study proposes model capable reaching large area or maintaining optimal electric field. design, modeling, 3D simulation, fabrication performed to analyze physical performance DSSH-SDD. electrical characteristics as-processed SDD chips, including leakage current, anode capacitance, resistor current under positive negative biases measured, resolution test at Tsinghua University. important indicator often expressed by full width half maximum (FWHM). results obtained can be applied future novel, flexible, large-area, high-resolution ionizing systems providing quantitative real-time information relative position spacecraft pulsars through radiation.

SiliSPECT: A Double-Sided Strip Silicon Detector-Based SPECT System

This work describes preliminary test studies with a dual-headed SPECT system that utilizes a new generation of silicon double-sided strip detectors (DSSDs) (Figure 1) with a 1-mm bulk thickness and larger active area (60 × 60 mm) as compared to standard gamma-ray silicon detectors. Furthermore, major improvements in the ASIC design make this detector very suitable for low-energy imaging of smal...

Low Noise Double - Sided Silicon Strip Detector for Multiple - Compton

A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gammaray universe in an energy band 0.1–20 MeV, which is not well covered by the present or near-future gamma-ray telescopes. The key feature of the SMCT is the high energy resolution that is crucial for high angular resolution and high background rejection capability. We have developed prototype modules for a l...

Double-Layer Silicon PIN Photodiode X-Ray Detector for a Future X-ray Timing Mission

A double-layer silicon detector consisting of two 500μm-thick silicon PIN photodiodes with independent readouts was mounted in a vacuum chamber and tested with X-ray sources. The detector is sensitive from 1–30 keV with an effective area of 6 mm. The detector performs best at −35 ◦C with an energy resolution of 220 eV (FWHM, full width at half maximum) at 5.9 keV, and is able to operate at room...

Characterization of a double-sided silicon strip detector autoradiography system.

PURPOSE The most commonly used technology currently used for autoradiography is storage phosphor screens, which has many benefits such as a large field of view but lacks particle-counting detection of the time and energy of each detected radionuclide decay. A number of alternative designs, using either solid state or scintillator detectors, have been developed to address these issues. The aim o...
