Micrometre resolution of a charge integrating microstrip detector with single photon sensitivity
نویسندگان
چکیده
A synchrotron beam has been used to test the spatial resolution of a single-photon-resolving integrating readout-chip coupled to a 320 µm-thick silicon strip sensor with a dedicated readout system. Charge interpolation methods have yielded a spatial resolution of σ(x) ≃ 1.8 µm for a 20 µm-pitch strip.

Many detection methods have been applied to detect radon gas. Due to the low noise and high resolution of gas detectors compared to semiconductor detectors or scintillation detectors, using them to detect alpha radiation is very considerable. Microstrip proportional detector is also included in this group and it has not been used for the detection of radon. In this article, response of the micr...
متن کاملX-Ray Imaging with a Silicon Microstrip Detector
A single photon counting X-ray imaging system, with possible applications to dual energy mammography and angiography, is presented. A silicon microstrip detector with 100 mm pitch strips is coupled to RX64 ASICs, each of them including 64 channels of preamplifier, shaper, discriminator and scaler. The system has low noise, good spatial resolution and high counting rate capability. Results on en...
متن کاملSpatial Resolution Measurements of Gallium Arsenide Microstrip Detectors
Results are reported from beam test measurements of one of the first commercial prototype gallium arsenide microstrip detectors. The detector consisted of 128 strips on a 50μm pitch, with a wafer thickness of 200μm. Operating at a bias of 180V, the detector produced a signal to noise ratio of 19 to 1, with a particle detection efficiency of better than 99%. The spatial resolution of the detecto...

Introduction: In nuclear medicine, the use of a pixelated semiconductor detector such as CZT is an of growing interest for introducing new devices. Especially, the spatial resolution can be improved by using a pixelated parallel-hole collimator with equal holes and pixel sizes based on the pixelated detector. The purpose of this study was to compare the effect of pixelated and ...
