Slow Scintillation Component and Radiation-Induced Readout Noise in Undoped CsI Crystals

by Fan Yang, Liyuan Zhang, Chen Hu, and Ren-Yuan Zhu


Because of its fast scintillation and low cost, undoped CsI crystal has been used to construct crystal calorimeters for high-energy physics experiments. Undoped CsI crystal samples from three vendors were investigated at the Caltech Crystal Laboratory. In addition to the 30-ns fast scintillation peaked at 310 nm, a slow scintillation component peaked at 450 nm was found with a decay time of a few microseconds. The intensity of the slow component may be varied from the seed to the tail end, so it affects crystal’s light response uniformity. It was also found that the slow component is highly correlated with the radiation-induced readout noise and may be eliminated spectroscopically by using an optical filter. The slow component is believed to be related to impurities and/or defects in the crystal. more...

Estimation of Parameters of Digital Radiography Systems

by S.P. Osipov, G.L. Zhang, S.V. Chakhlov , M.M. Shtein, A.M. Shtein, V.B. Trinh, and E. Sirotyan

Based on the test object and the given data from the detectors, a set of formulas connecting the characteristics of digital radiography (DR) systems with the parameters of the X-ray radiation source is checked. The obtained formulas can give a rational choice of the source and the X-ray detector for a nondestructive test. A series of calculations for the DR characteristics of systems based on the CdWO 4 panel detectors with the 0.3-mm thickness for medium and high X-ray energies was carried out. A series of experiments was carried out to determine the X-ray attenuation rate with the maximum energies of 4.5 and 9 MeV for steel plates with a mass thickness from 20 to 80 g/cm 2 . A comparison of the experimental and calculated data on the attenuation rate showed a good convergence for the range of mass thicknesses of the test object fragments. The calculation results and the results of experimental studies prove the correctness of the proposed method for calculating and evaluating the basic parameters of DR systems under the condition of rigid slit collimation of X-ray radiation for inspection of large objects from highly scattering materials. more...
