Chronicles of the 2022 Baikal Expedition. Operating the Marking Winch

Maksim Kolbin, a DLNP mechanic of test benches and facilities, is operating the marking winch. The marking winch is used to mark and cut supportive cables of strings.

Chronicles of the 2022 Baikal Expedition. Filming under the Ice

Today, we checked the track previously cleared for laying the bottom cable to the shore. There are two pressure ridges on the way. The milling cutter cuts the ice to the depth less than a metre, that is why we have to take a look under the ice using the GoPro camera to make sure that there are no hidden obstacles that could cause the breakdown of the cable.

Lake Baikal, 6 March 2022. Mounting optical modules on String 4 of Cluster 9 by the team of Bair Shaybonov, Vladimir Shatunov, Dmitry Zaborov and Yury Malyshkin.

Unique Lenses for the Unique Facility

The TAIGA project in which DLNP researchers are actively involved is aimed at studying the high-energy region of the gamma radiation spectrum of the Universe. The main objective of the project is searching for the origins of cosmic rays in the range between 1014 and 1018 eV. The experiment is located near the Southern edge of Lake Baikal on the astrophysical site in the Tunka valley (Republic of Buryatia) and comprises several facilities that measure parameters of extensive air showers resulting from interactions of cosmic and high-energy gamma rays with the atmosphere.

The First New Timepix4 Pixel Chip

Scientists from the Dzhelepov Laboratory of Nuclear Problems involved in the Medipix Collaboration have manufactured the first new Timepix4 pixel chip which provides a long-expected opportunity to proceed from “paper work” to studying chip characteristics. It will allow us to develop detectors for the use in experimental facilities while conducting fundamental and applied research.

The annual expedition to build the Baikal-GVD, the deep underwater neutrino telescope of a cubic-kilometre scale, is in full swing. During about two months, the Baikal-GVD collaboration is intending to deploy two new clusters with optical modules, to repair and upgrade the previously installed clusters, and to proceed with the development of the optical data transmission system within the facility.

Congratulations to Alexi Gongadze on the Successful Defence of the Candidate Dissertation!

On 25 February 2022, at the session of the DLNP Dissertation Council, Alexi Gongadze defended the dissertation “Development and design of large-area tracking systems for the muon spectrometer of the ATLAS experiment with the Large Hadron Collider” for the degree of the Candidate of Physics and Mathematics in Specialty 01.04.01: Instruments and methods of experimental physics. Our congratulations to Alexi on the successful defence of the candidate dissertation! We wish him further scientific achievements and success!

Scientific Cooperation of JINR and Cuban Centres CEADEN and CENTIS

The research on high-resolution X-ray and single-photon emission tomography imaging of small animals is underway at the Dzhelepov Laboratory of Nuclear Problems within the joint Russian-Cuban project “High-Resolution SPECT/CT Method Based on Medipix Detectors” (Single-Photon Emission Computed Tomography/Computed Tomography). We have talked to the scientists involved into the project about their work, how technologies from fundamental science reach out into applied areas, and how productive international projects can come to life.  

JEMS-20 Participants Visited Our Laboratory

Last Friday, on 18 February 2022, participants of the 20th International Training Programme for Decision-Makers “JINR Expertise for the Member States and Partner Countries” (JEMS-20) visited our Laboratory. This time, heads and specialists from research and education institutions of Armenia, Slovakia, Serbia and North Macedonia came to attend the training programme.  

“Strana ROSATOM”: A Tomograph for Mice Developed at JINR

On 17 January 2022, the article “A tomograph for mice has been developed at JINR” was published in the newspaper “Strana ROSATOM”: https://strana-rosatom.ru/2022/02/17/v-oiyai-izobreli-tomograf-dlya-myshej/ Experts from the Joint Institute for Nuclear Research and the Cuban scientific centres CENTIS and CEADEN have developed a technology that will improve the spatial resolution of single-photon emission computed tomography. It matters a lot to pharmaceutical scientists. We have talked to the project authors.
