Russia, knowledge, Italy, research, experience

Russian scientists have developed a hybrid material that can be used to make projectiles for detectors to intercept dark matter particles. The material can detect and absorb external radiation. The results of the study were published in the journal “Materials”.

The material, which was developed on the basis of plastic and the rare earth metal gadolinium, is to be trialled as part of an international project Dark Side 20 kg Dedicated to detecting dark matter. This trial is scheduled to begin in Italy between 2025 and 2026.

According to various estimates, all the matter that make up planets, stars, galaxies and interstellar gas makes up five to 15 percent of the mass of the universe. The rest is said to be dark matter, which in no way interacts with electromagnetic waves, and therefore remains invisible to most existing devices. Since dark matter is involved in gravitational interactions, scientists are convinced of its existence. Otherwise, it would be difficult to explain the atypical behavior of some galaxies, as well as the optical disturbances in some stars and many other astronomical phenomena.

So far, no dark matter particles have been recorded, even indirect signs of it. Despite all this, new experiments are constantly being carried out in which the interactions of these particles with atoms of ordinary matter are determined.

One of the DarkSide experiments was conducted at the Gran Sasso National Laboratory in Assergi, Italy. Researchers will attempt to trap dark matter particles in massive target chambers filled with inert argon gas. According to the hypothesis of scientists, dark matter particles can collide with argon atoms as they travel through the respective target chamber and scatter there, thereby revealing their presence in the form of characteristic signals.

In order to separate dark matter signals from other events, such as penetration of cosmic rays, target chambers are placed deep within the Earth. However, one problem is that high-energy neutrons, which are released during the fission of uranium or other radioactive materials that mix with the material for the production of detector shells, can get into the detector.

Russian scientists – employees of the Mendeleev University of Chemical Technology, MGU Moscow State University, the United Institute for Nuclear Research and Belgorod Research University – proposed a hybrid material polymethylmethacrylate (also known as organoplastic glass) for the experiment. This inexpensive material with a small background radiation also contains large amounts of hydrogen, whose atoms help to trap strange background neutrons.

Another component of the newly developed material is the rare earth metal gadolinium, which is a refractory element neutrons More effective in absorption compared to other non-radioactive materials.

Igor Avitisu, chair of the Christlin Chair in Chemistry and Technology at Mendeleev University, also said that a 20-ton chamber of liquid argon is being built in the Gran Sasso underground laboratory, which is likely to intercept dark matter particles. “This room needs an envelope that can swallow thermal neutrons so that they do not affect the interaction of dark matter particles with argon nuclei.”
