The scintillator crystal is a crystalline material that can light under the influence of high-energy rays and be widely used for detecting particles. With development industrial CT other fields, demand inorganic crystals with high melting points performance increasing yearly, which results in abandonment traditional laboratory mode manufacturing crystals. For achieving needs high-standard cryst...

Abstract The scintillation properties of Hf-based oxide materials are reviewed briefly. In particular, we focused on the undoped, Ti-doped, and rare-earth-doped HfO 2 , M 3 ( = Ca, Sr, Ba), RE Hf O 7 La, Gd, Lu). explained here spectra, decay, light yield estimated by measurement pulse height distribution. Further, synthesis methods material single crystals transparent ceramics included in this...

A combined y-ray probe@* imaging detector was created by modification of a beta imaging intra-operative probe. This phoswich detector consists of a thin CaF,(Eu) p*imaging disk, coupled through a light diffuser to 7 or 19 parallelepiped highZ scintillation crystals arranged hexagonally in columns. These elements are either 2 x 2 ~ 1 0 mm3 or 4 x 4 ~ 1 0 mm3 LSO, GSO or BGO crystals, and act as ...

We have measured scintillation properties of pure CsI crystals used in the shower calorimeter built for a precise determination of the π→πeνe decay rate at the Paul Scherrer Institute (PSI). All 240 individual crystals painted with a special wavelength-shifting solution were examined in a custom-build detection apparatus (RASTA—radioactive source tomography apparatus) that uses a 137Cs radioact...

Applications that utilize scintillation detectors at low temperatures are growing in number. Many of these require materials with high light yield and a fast response. Here we report on the low-temperature characterisation ZnSe doped Al or Te, respectively. The X-ray luminescence decay curves were measured over 77–295 K temperature range, alpha particle excitation was used to examine output kin...

  Introduction: Arrays of segmented scintillation crystals are useful in megavoltage x-ray imaging detectors for image-guided radiotherapy. Most previous theoretical studies on these detectors have modelled only ionizing-radiation transport. Scintillation light also affects detector performance. ScintSim1, our previously reported optical Monte Carlo code for such detector...

PET (Positron-emission tomography) is used to determine physiological and metabolic functions in the body. Monte Carlo simulation an important part of imaging, Particle Heavy Ion Transport code System (PHITS) a platform that can be perform simulations. This study uses based on PHITS range gamma absorption with energy 511 keV scintillation detector crystal material. The determines effective leng...
