Phoswich detectors were developed to detect low-intensity, low-energy gamma rays, X-rays, as well as alpha and beta particles efficiently in a higher-energy ambient background. Some detector designs can measure and separately identify all energies simultaneously. A phoswich ('phosphor sandwich') is a combination of scintillators with dissimilar pulse shape characteristics optically coupled to each other and to a common PMT (or PMTs). Pulse shape analysis distinguishes the signals from the two scintillators, identifying in which scintillator the event occurred. In 2010 development of a monolithic phoswich sensor technology was announced, departing from the discrete designs. This novel development, termed the Continuous Phoswich scintillator and detector, provides a number of bits of depth-of-interaction (DOI) information, a significant improvement over the 1 to 2 bits available previously with discrete phoswich scintillators. ==References== *(Characterization of Phoswich Scintillation Detectors for the Focal Plane Hodoscope of Magnetic Proton Recoil Spectrometers for Fusion Neutrons ) *(DIGITAL PULSE SHAPE ANALYSIS WITH PHOSWICH DETECTOR S TO SIMPLIFY COINCIDENCE MEASUREMENTS OF RADIOACTIVE XENON ) *(APPLICATION OF PHOSWICH DETECTORS FOR LUNG COUNTING PLUTONIUM-238 ) * *(STUDY OF A TRIPLE-LAYER PHOSWICH DETECTOR FOR BETA AND GAMMA SPECTROSCOPY WITH MINIMAL CROSSTALK ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「phoswich detector」の詳細全文を読む スポンサード リンク
