An experimental investigation of double-slit dynamic X-ray diffraction in silicon crystals demonstrates that Young’s interference fringes can be formed in the cross section of the reflected beam, depending on the distances between the monochromator and the slits, as well as between the slits themselves. The study reveals that the number of observable fringes is influenced by both the crystal...
As is known, the correct choice of the deviation function is very important in order to obtain a certain intensity, spectral and spatial distribution in the diffracted beams formed as a result of X-ray diffraction in deformed crystals. To describe the deviation function, it is sufficient to provide the dependence of the bending radius and interplanar distances of the reflecting atomic planes...
Preclinical positron emission tomography (PET) requires high spatial resolution of the detector. A monolithic scintillator detector block is one of the promising approaches due to its ability to estimate the depth of interaction (DOI) and improve resolution through processing multiple channels and analyzing light distribution. The typical construction of such a block is a matrix of silicon...
Semiconductor nuclear radiation detectors are mostly high-resistance. In order to use very high-resistance detectors, we propose an interface for working with them. We propose a metal-oxide-semiconductor (MOS) structure as a signal-modulating device. The modulation of the MOS capacitance occurs by modulating illumination through an optically translucent metal contact.
