This reaction is endothermic, its threshold is 6.63 МeV, and the cross-section is 4·10 сm. Li nucleus with Т1/2=0.847 s is transformed into two α-particles of 1.5 МeV energy each, and one β-частицу of energy 13 МeV. The light yield in a plastic scintillator due to capture of thermal neutrons from α-particles and Li nuclei is equivalent to the yield from γ-quanta or electrons of energies from 65...

The BACON liquid argon (LAr) scintillation detector prototype will be used to measure 1 2 intensity, promptness , and decay behavior for pure LAr and xenon (Xe) doped LAr mixtures. 3 The goal is to aid in planning, cost reduction, and improved detection for the Deep Underground Neutrino Experiment (DUNE) [6]. The scintillation of LAr is in the vacuum ultra-violet (VUV), requiring detectors to u...

Aims Studying this chapter should give you some appreciation of the variety of radiation detectors available and equip you with some practical knowledge about their characteristics and uses. This chapter also contains practical knowledge about the description and measurement of the effects of radiation on humans. You should learn how the problem of measuring doses is currently handled in terms ...

Gamma transparent materials are necessary to avoid detection Development of a small area (1-2 cm2) in situ beta imaging device includes optimization of the front end scintillation detector which is fiber optically coupled to a remote photon detector. Thin plastic scintillation detectors, which are sensitive to charged particles, are the ideal detectors due to the low sensitivity to ambient gamm...

This article describes CLEAN, an approach to the detection of low-energy solar neutrinos and neutrinos released from supernovae. The CLEAN concept is based on the detection of elastic scattering events (neutrino-electron scattering and neutrinonuclear scattering) in liquified noble gases such as liquid helium, liquid neon, and liquid xenon, all of which scintillate brightly in the ultraviolet. ...

An upgraded version of the OGRAN—combined optical-acoustic gravitational wave detector has been investigated in a long-term operation mode. This installation, located at Baksan Neutrino Observatory (BNO) INR RAS, is designed to work under program for detecting collapsing stars parallel with neutrino detector: Underground Scintillation Telescope (BUST). Such joint search corresponds modern trend...

Scintillation single crystal fibers (SCFs) have great potential applications in the new generation of high-energy ray and particle detectors due to their morphological advantages. In this work; Ce:LuAG SCFs with a diameter 1 mm were grown along direction [111] by laser-heated pedestal growth (LHPG) method using transparent ceramic as source rod; doping concentration was 0.1 at%, 0.3 respectivel...
