"Beer for Trade Union Members Only!"

This quote from “The Twelve Chairs” has long become a meme. It reflected the reality of the late 1920s— trade union members enjoyed not only beer but also other benefits. Benefit distribution was the trade union domain for all long decades of the USSR existence. Since every employee of the country was a trade union member starting with a student, so benefits could be enjoyed by everyone.

First Experimental Proof of Theorized Nuclear Fusion Processes in Massive Stars

The international Borexino Collaboration has announced the first observation of neutrinos from the CNO process in the Sun, which experimentally confirms the second mechanism for energy generation in stars. Earlier, only neutrinos from the proton–proton cycle were observed. This discovery is highly important for astrophysics since in stars more massive than the Sun energy is mainly produced through the CNO cycle. The results of the investigation are published in Nature.

A New Method for Measurement of Low Neutron Fluxes using Iodine-Containing Scintillators

One of the most important objectives pursued in low-background experiments on the search for rare events is the study and continuous monitoring of neutron fluxes in the vicinity of the detection setup. The problem is that neutron fluxes in low-background experiments are thousands of times lower than on the ground. The gold standard for neutron flux measurement is the 3He-based counter due to a large cross section for thermal neutron capture (5333 b) and extremely low sensitivity of these counters to the gamma background. Unfortunately, there are no commercial 3He sources: its content in natural helium is only 0.000137%. All the available amount of 3He is produced at nuclear reactors, and its cost is more than $2000 per litre.

Adjustment and Preparation for Commissioning of the Electron Linear Accelerator LINAC-200

At DLNP, the adjustment and commissioning work is well under way at LINAC-200, the first stage of the electron linear accelerator LINAC-800. The accelerator is intended for carrying out methodological investigations of detectors developed at JINR, solving applied problems with the use of electron beams, and implementing educational programmes of the JINR University Centre. The accelerator will produce electron beams with energies of 10 MeV to 200 MeV in a wide intensity range.

Neutrino Geophysics at DLNP

Neutrino geophysics has evolved to a separate discipline not so long ago. This rapidly developing branch of science at the intersection of geology, geophysics and particle physics examines the Earth’s interior by observing antineutrino fluxes produced by the decay of radioactive elements in the Earth’s crust and mantel. The contribution of radioactive decays to the total heat release of the Earth (radiogenic heat) determines the heat history of the Earth and restricts its geophysical models.

Photography Exhibition “Baikal. Neutrino Hunters” by Bair Shaybonov in the Mir Culture Centre Goes On

The article about the photography exhibition by Bair Shaybonov “Baikal. Neutrino Hunters” was published in the JINR weekly newspaper “Dubna: Science, Community, Progress”. Do you want to enjoy amazing scenery of Baikal in winter? And to touch a glass sphere, an optical module to be submerged deep under the water? Visit the Exhibition Hall of the Mir Culture Centre where the photography exhibition “Baikal. Neutrino Hunters” has been recently launched. The photographer is a regular member of the International Baikal collaboration Bair Shaybonov. The exhibition is open till 30 October.
