Additive manufacturing of inorganic scintillator-based particle detectors

Inorganic scintillators are widely used for scientific, industrial and medical applications. The development of 3D printing with inorganic scintillators would allow fast creation of detector prototypes for registration of ionizing radiation, such as alpha and beta, gamma particles in thin layers of active material and soft X-ray radiation. This article reports on the technical work and scientific achievements that aimed at developing a new inorganic scintillation filament to be used for the 3D printing of composite scintillator materials: study and definition of the scintillator composition; development of the methods for the inorganic scintillator filament production and further implementation in the available 3D printing technologies; study of impact of the different 3D printing modes on the material scintillation characteristics. Also, 3D printed scintillators can be used for creation of combined detectors for high-energy physics.Comment: 14 pages, 16 figure

Small-sized UV radiometer on the basis of schottky diodes

In this work, main characteristics are considered of photosensitive Schottky diode structures – n-type ZnSe(Te,X)/Ni, where Х = O or Al, which are promising as ultraviolet radiation detectors in the 200–480 nm range. The Schottky barrier-based sensors show good sensitivity in the short-wave regions of the ultraviolet range, are practically insensitive to solar radiation at wavelengths above ∼460 nm, have rather short response time (∼1 ns) and quantum efficiency of up to 70%. Typical values of the monochromatic current sensitivity Sλ in the 420–440 nm range is 0.1–0.15 А/W. Characteristics were studied of detectors using glass and interference light filters for singling out biologically active regions of A, B and C of ultraviolet spectrum. Testing results of our ultraviolet radiometer have shown that the developed experimental sample meets the requirements to the instruments of this class
