23.05.2018 г. в рамках 11-ой стажировки молодых ученых и специалистов стран СНГ, организованной Международным инновационным центром нанотехнологий СНГ при поддержке Межгосударственного фонда гуманитарного сотрудничества государств – участников СНГ, Николай Анфимов прочитал лекцию для участников стажировки и провел экскурсию в ЛЯП.
The year 2017 marked the 25th anniversary of the world’s largest scientific collaborations, the ATLAS collaboration, established in 1992 for carrying basic research at the Large Hadron Collider at CERN. JINR joined the preparations for the international ATLAS experiment as early as the preliminary R&D stage and became one of its main participants. The film is dedicated to this significant event.
On May 16, 2018, within the framework of the Dubna visit of Prof. K. Jakobs, spokesperson of the ATLAS experiment at the LHC, a meeting of the JINR participants in the ATLAS Collaboration was held.
The results and plans of physics research in the fields of the Standard Model, Higgs boson physics, search for new physics, and heavy quark physics were presented, and the prospects for the JINR participation in the operation of the facility and its upgrading during the upcoming technical shutdown were discussed. Also, readiness of JINR for manufacture of MicroMegas detectors was demonstrated to Prof. K. Jakobs.
ATLAS spokesperson Prof. K. Jakobs speaks about his seminar at DLNP on 16.05.2018, where he presented the results and further plans of research within the ATLAS project at the LHC.

Nikolai Azaryan speaks about a pilot batch of elliptical single-cell superconducting cavities for the frequency of 1.3 GHz manufactured by hydroforming and electron-beam welding of highly pure niobium. The manufactured cavities feature long stable superconductivity. The measured figure of merit is no less than 10^10.

Congratulations to Aleksandr Simonenko on successful defence of the candidate of science dissertation!
On 27 April 2018 at the session of the DLNP Dissertation Council Aleksandr Valerievich Simonenko defended the dissertation “Development of a control system and study of characteristics of CDFII muon counters for experiments at the Tevatron” for getting the degree of the Candidate of Sciences in Physics and Mathematics under speciality category 01.04.01: instruments and methods of experimental physics.
We heartily congratulate Aleksandr on the successful defence of the dissertation and wish him new creative achievements!
The DarkSide-50 experiment is aimed at searching for dark-matter weakly interacting particles (WIMPs) with a large mass (>50 GeV), where a critical fact is the possibility of separating the signal from the possible background. The recently accomplished analysis of the data collected for 532 operation days of the facility days demonstrated unique capabilities of suppressing the background in the detector. An additional analysis of the low-energy region of the spectrum of the ionization events demonstrated that the DarkSide-50 detector was sensitive to low masses (<10 GeV) of dark-matter particles. These results add more confidence in that the observation of a positive signal in the second-generation facility, such as the projected DarkSide-20k experiment, will really mean observation of particles of a new nature.

On 27 April 2018, a regular ATLAS weekly working meeting was held at DLNP. O.A. Koval’ (group headed by I.R. Boiko) made a report on the status of the investigations into associative production of the top quark and the Higgs boson. Since this Higgs boson production channel has not been observed yet, the projected research seems to be promising from the point of view of both the investigations of the Standard Model and the search for new physics in the experiments at the LHC.More photos
