"The main research directions of paleoecology"
A.V. Pakhnevich
Alexey Valentinovich Pakhnevich PhD in Biology, Senior Researcher Paleontological Institute, named after A.A., Borisyak, RAS
Paleoecology is the science that studies the interactions of extinct organisms with each other and with the environment. The report will be devoted to the analysis of the relationship of ancient organisms in populations and communities (= biocenoses). Examples of trophic connections, reconstruction of habitat conditions by finding characteristic species of plants and animals, the content of various minerals, chemical elements and their isotopes in the skeletons will be considered. The study of these issues is associated with the use of modern research techniques. Examples of their use will be demonstrated in the report.

"Application of neutron activation analysis and other methods in materials science"
Aleksiayenak Y.V.
The report will present the results of work carried out jointly with the Scientific-Practical Materials Research Centre of the National Academy of Sciences of Belarus (SSPA "Scientific-Practical Materials Research Centre"), Minsk, Belarus. Currently, the fields of application of composite materials (composites) are very wide, ranging from mechanical engineering to electronics. Composites based on copper disulfide, which serves as the basis for solar energy converters; composites based on cubic boron nitride, Ti, and Al, which can be used in high-energy and high-temperature electronics, solid-state dosimetry, have been investigated. The obtained composites were analyzed by X-ray diffraction and scanning electron microscopy. Neutron activation analysis was used to determine impurities in composite materials synthesized at the Scientific-Practical Materials Research Centre, to determine the optimal conditions for synthesis, and to identify sources of impurities, for that purpose the elemental composition of the synthesis equipment and burden materials was studied.

"ACCELERATOR LUE-200. YESTERDAY TODAY TOMORROW"
A.P. SUMBAEV (Veksler and Baldin Laboratory of High Energy Physics JINR)
The linear electron accelerator LUE_200 was designed and created as a driver for a booster-type neutron source with an integral neutron yield of ᷉ 1014 sec-1, which determines the energy and power of the accelerated particle beam. The accelerator was put into operation in stages. 2009 - 2010 the physical start-up of the IREN facility was carried out as part of the first stage of the accelerator (one accelerating section, one klystron, one modulator). The first stage of the accelerator worked several thousand hours for the experiment at a cycle frequency of 10 - 25 Hz with a beam current of 1.5 - 2.0 A, duration ᷉ 100 nsec and an energy of 30 - 35 MeV (spectrum maximum). In 2016, the second accelerating section was installed and launched (+ 2nd klystron with modulator). As a result of the launch of the second stage of the accelerator (2016-2019), an increase in the energy of accelerated electrons to 70 MeV, and the average power of the electron beam to 0.6 kW was achieved. The problems of achieving design parameters and the possibility of developing an accelerator are considered. The plans for the development of the accelerator provide for an increase in the cyclicity of the accelerator up to 100-120 Hz, and the beam power up to 1.5 kW, which will make it possible to obtain up to 3 ∙ 1012 sec-1 neutrons on a non-multiplying W target.
The theses submitted for defense and the results included in the thesis for the degree of Doctor of Technical Sciences are presented for discussion.

Specialized course "The HERCULES Specialized Course (HSC)", May 31 - June 9, 2021, online
The event "The HERCULES Specialized Course (HSC)" on the use of neutrons and synchrotron radiation for condensed matter research has been held since 2006 as a supplement to the well-known HERCULES European School (http://hercules-school.eu/).
This year, the HERCULES Specialized Course (HSC) will be held online from May 31 to June 9.
The organizers of the event are the Central European Research Infrastructure Consortium (CERIC-ERIC, the leading distributed European infrastructure in the field of materials science), the projects ACCELERATE and CALIPSOplus of the “Horizon 2020” program.
The specialized course is an extensive training combining theory and practice. Lectures will be delivered by leading experts from the CERIC-ERIC partner organizations.
Researchers will have the opportunity to expand their scientific knowledge of large research infrastructures and learn more about the various methods offered by the CERIC-ERIC partner centers.
Target audience: researchers from any country in the world, primarily, young researchers (post-graduate students and postdocs) in the field of physics, chemistry and biology.
Registration is open.
The 1st stage of registration: until April 26; notice from organizers: May 7
The final registration deadline: May 17, notice from organizers: May 24
