“…Besides the 40 K and 208 Tl peaks, due to the natural contaminations of the environment, only contaminations in 75 Se ( 1/2 = 119.8 d, -value = 863.6 keV) and 65 Zn ( 1/2 = 244 d, -value = 1359.9 keV) were found. The presence of these isotopes, due to the activation of 74 Se and 64 Zn, respectively, does not affect the background in the DBD region because of their short half-lives and low -values.…”

In the field of fundamental particle physics, the neutrino has become more and more important in the last few years, since the discovery of its mass. In particular, the ultimate nature of the neutrino (if it is a Dirac or a Majorana particle) plays a crucial role not only in neutrino physics, but also in the overall framework of fundamental particle interactions and in cosmology. The only way to disentangle its ultimate nature is to search for the neutrinoless double beta decay. The idea of LUCIFER is to combine the bolometric technique proposed for the CUORE experiment with the bolometric light detection technique used in cryogenic dark matter experiments. The bolometric technique allows an extremely good energy resolution while its combination with the scintillation detection offers an ultimate tool for background rejection. The goal of LUCIFER is not only to build a background-free small-scale experiment but also to directly prove the potentiality of this technique. Preliminary tests on several detectors containing different interesting DBD emitters have clearly demonstrated the excellent background rejection capabilities that arise from the simultaneous, independent, double readout of heat and scintillation light.

“…According to [4][5][6][7], the band with a maximum at 630 nm is due to a complex center including a zinc vacancy. A band with a maximum at 970 nm is due to a complex center with a vacancy of selenium or an admixture of copper [8,9].…”

1The luminescence spectra of high-resistance ZnSe crystals consist of two main bands with maxima at 630 nm (1.92 eV) and 970 nm (1.28 eV). The planned comparison has been carried out between the spectra of X-ray luminescence and photoluminescence of ZnSe among themselves in the spectral region from 400 to 1200 nm at different excitation intensities and different temperatures (8, 85, 295, and 420 K). It is found that the forms of luminescence bands do not depend on the excitation intensities. The band form with a maximum at 970 nm also does not depend on the excitation type, and the band at 630 nm differs slightly under the X-ray and UV excitations. The temperature dependences of the spectral positions of bands' maxima and their half-widths are analyzed. A conclusion is drawn that the 970-nm emission band is elementary. A short-wavelength shift of the spectral maximum of the 630-nm band with increasing the temperature makes it possible to conclude that this luminescence band is non-elementary. This correlates with the previously discovered feature of this band related to the realization of two recombination mechanisms (electron and hole) at this luminescent center.K e y w o r d s: spectra of X-ray luminescence, spectra of photoluminescence, center of recombination, temperature dependences of the spectral position of the maximum and half-width of the band, zinc selenide.

“…The GE Gemstone TM has been the first garnet-scintillator introduced commercially for CT detection. Another group of materials, evaluated for the Philips dual-layer detectors, are low-Z scintillators such as ZnSe:Te, used for detecting the low-energy part X-ray spectra [39]. Examples of rawmaterial (wafer) samples of a garnet-type, GOS, and ZnSe:Te scintillators are demonstrated in Fig.…”

“…The top scintillator layer's atomic number and thickness have been optimized to maximize energy separation at 140 kVp, while maintaining high enough signal statistics for the low-energy raw data even for a large patient. ZnSe advantage in light yield [39] (*70 % better than GOS) contributes to a high SNR in the top (low-energy) layer detector, enabling it to function at very low dose without causing artifacts, typical to electronic-noise dominant signals.…”

State of the Art of CT Detectors and Sources: A Literature Review

View full text Add to dashboard Cite

The three CT components with the greatest impact on image quality are the X-ray source, detection system and reconstruction algorithms. In this paper, we focus on the first two. We describe the state-of-the-art of CT detection systems, their calibrations, software corrections and common performance metrics. The components of CT detection systems, such as scintillator materials, photodiodes, data acquisition electronics and anti-scatter grids, are discussed. Their impact on CT image quality, their most important characteristics, as well as emerging future technology trends for each, are reviewed. The use of detection for multi-energy CT imaging is described. An overview of current CT X-ray sources, their evolution to support major trends in CT imaging and future trends is provided.
