Development of Solid-State Detector for X-ray Computed Tomography
Solid-state detector has recently been used for x-ray Computed Tomography (CT) because it has high light conversion efficiency, quantum efficiency and compact size, compared with Xenon gas detector. In order to reduce radiation dose to the patient in medical x-ray CT, it should be needed to maximize the quantum efficiency and signal-tonoise ratio (SNR) of the detector. In this study, 16-channel...
متن کاملSolid-state light-phase detector
Attosecond science relies on the use of intense, waveform-controlled, few-cycle laser pulses1 to control extreme nonlinear optical processes taking place within a fraction of an optical period. A number of techniques are available for retrieving the amplitude envelope and chirp of such few-cycle laser pulses. However, their full characterization requires detection of the absolute offset between...
متن کاملAdvanced Solid State Detector Technologies for Particle Detection
Preliminary experimental results obtained with hydrogenated amorphous silicon (a-Si:H) films are presented. This material has been selected for its unique capability to be deposited on top of integrated circuits and for its excellent radiation hardness. Particle sensors using vertical integration technology were produced. The Macropixel sensor showed a noise of 41e r.m.s. at a peaking time of 1...
متن کاملPrototype Direction-Sensitive Solid-State Detector for Dark Matter.
A prototype weakly interacting massive particle (WIMP) detector system is described. The detection efficiency is much larger when the incident neutral particle flux is perpendicular to the detector plane than when it is parallel to the plane. A greatly scaled-up system based on this device would therefore be sensitive to the diurnal rotation of the “WIMP wind” produced by the solar system’s rap...
متن کاملSolid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
