The TUC detector was launched on board the Lomonosov satellite from the Vostochny Cosmodrome and put into the sun-synchronous orbit on 28 April 2016. Measurement of the spectrum, mass composition, and anisotropy of the Ultrahigh-Energy Cosmic Rays (UHECRs) with the energy E ~ 10^20 eV (1000 times higher than the LHC energy) and search for UHECR sources are among the most important tasks of high-energy astrophysics.
Daya Bay Analysis Workshop at the Beijing Institute of High-Energy

On 19–21 April 2018, the Daya Bay Analysis Workshop is held at the IHEP in Beijing. The results to be presented in the summer are discussed.
Daya Bay is the first experiment to discover disappearance of reactor electron neutrinos because of mixing with the third mass state at the confidence level of more than five standard deviations and the first reactor experiment to measure neutrino mass splitting Δm²₃₂. Up to date, the Daya Bay measurements of both parameters are best in precision. Eight identical detectors, each with 20 t of liquid gadolinium scintillator, are used in the experiment. The detectors are located on three experimental sites and measure the flux and spectrum of electron antineutrinos coming from six nuclear reactors with a total heat power of 17.4 GW. The characteristic distances between the reactors and the detectors are 500 m, 600 m, and 1.5 km.
Workshop on JUNO Top Tracker held at DLNP

The workshop on the JUNO Top Tracker at DLNP entered its second day. JINR has been participating in the JUNO collaboration for about three years. In 2020, the reactor neutrino experiment is to be launched in China. Now the construction of the Jiangmen Underground Neutrino Observatory is well under way 150 km away from Hong Kong. The experimental hall will be 700 m underground. The detector filled with 20 000 t of liquid scintillator will be viewed by about 18 000 photomultiplier tubes 20 in. in diameter and 25 000 photomultiplier tubes 3 in. in diameter to detect scintillation light resulting from antineutrino interactions in the detector. The main goal of the experiment is to determine the neutrino mass hierarchy by precision measurement of neutrino oscillations.

The participants came from Vietnam (University of Dalat, Dalat Nuclear Research Centre), Italy (INFN), Cuba (Cuba’s Isotope Center), Russia (North-Ossetian State University, Moscow Institute of Steel and Alloys), and South Africa (IThemba LABS).
Seminar “Nanoworld of the genes and the genome before and after the radiation “blow” (100 rad = 1 Gy and more)” by Igor Donatovich Aleksandrov
- Details
- Category: Новости проекта "Проект РАДИОГЕН"
Genetic effect of ionizing radiation on generative cells (gametes) is characterized not only by a diversity of observed changes in individual genes and the genome as a whole but also by the danger that these changes constitute for the coming generations.
The observed diversity stems from both the features of the DNA organization of the nanotarget (gene) and the microtarget (genome) and the character of the ionizing particle energy distribution in these targets. The topics covered at the seminar were modern concepts of the gene and genome DNA organization, energy distribution in the genome (within the modern track structure theory), and the spectrum of primary (theoretically expected0 and observed (from the sequence analysis of radiation-induced mutations) inherited DNA changes.
