From this issue you will learn how the ANTARES facility was put out of service, in which way the 2022 winterover team gathered at the South Pole, which tasks were performed on the deep-underwater platform of KM3NeT/ORCA during sea operations, and also, you will find the summary of papers on neutrino astronomy here.

On 25 March 2022, an event devoted to the 66th anniversary of the foundation of the Joint Institute for Nuclear Research was held at the JINR Scientists’ Club. The Head of the DLNP Experimental Department of Particle Physics Alexander Grigorevich Olshevskiy and the chief DLNP researcher Nikolay Artemevich Rusakovich were granted the Medals of the Ministry of Science and Higher Education “For Impeccable Labour and Excellence” III class.
The second bottom cable is being laid from the telescope to the shore. Mikhail Milenin’s team is in action. About two kilometres are left behind during one day.
The new winch has been assembled on the ice near the shore.

The series started with a lecture by the chief engineer of the Dzhelepov Laboratory of Nuclear Problems Sergey Yakovenko. He explained to students and schoolchildren from the Arkhangelsk Oblast the JINR developments in tumour treatment and the design of the future medical superconducting cyclotron for proton therapy which is two or three times more effective than photon therapy. The lecture awoke a genuine interest. Attendees were eager to know how nuclear physics is connected to medicine, how irradiation accuracy will be achieved and whether the synchrophasotron constructed in the middle of the last century will still be used.
Buoys, plastic hollow orbs, provide positive buoyancy. There are two types of buoys. Orange buoys hold the string vertically, green ones horizontally support crosspieces between the central and peripheral strings.
Today, eight newly mounted strings of Cluster 9 have been tested. All of them are connected in a regular way. Preparations for laying the bottom cable of Cluster 10 are finished. The first 700 m of this cable are laid. Cluster 7 is repaired, and data taking is resumed.
On 4 March 2022, two compact precision laser inclinometers (CPLIs) designed at the Experimental Department of Multiple Hadronic Processes at the Sector of Mikhail Vasilevich Lyablin were transported to the experimental hall of the MPD NICA detector. The main objective of the operational start of two inclinometers is determining the level of angular microseismic vibrations in the immediate vicinity of the MPD detector, and later, with an inclinometer network developed, along the entire perimeter of the NICA collider.
One can imagine that the Baikal Neutrino Telescope is nothing more than just optical modules. Cables play a key role as well — they supply clusters with voltage and transmit signals. Each string comprises about 4.5 km of cables. That is, the entire telescope with 10 clusters (eight strings in each) will have about 360 km of cables at the end of the expedition. And this is without considering those lines that run to the shore.
The JINR Department of Licenses and Intellectual Property announces that on 3 February 2022, the Joint Institute for Nuclear Research received a patent for the invention “Method for changing the final energy of a proton beam used for FLASH radiotherapy”. The authors are Sergey Nikolaevich Dolya and Viktor Ivanovich Smirnov. We congratulate our colleagues on being granted the patent!
The expedition to construct the Baikal-GVD Deep Underwater Neutrino Telescope is underway. Igor Stepkin, an expedition member, wishes happy Women’s Day on behalf of all Baikalians: Dear women, fair ladies! The Baikal expedition members wish you happy Women’s Day! We sincerely admire you, your beauty, charm and wisdom and heartily wish you the brightest things in the world! Keep on smiling! May your spirits always be high!
