Yuri Andreevich Usov

• Has been working at DLNP, JINR, since 1973 after graduation from the Leningrad Refrigeration Institute as a qualified specialist in cryogenic engineering and deep freezing.
• Scientific activities are closely related to physical and methodological research on producing ultralow temperatures to be used in physics experiments.
• A winner of two first and several second prizes of the JINR Competition of Scientific Council.
• Worked his way from a trainee to the head of the DLNP Sector of Low Temperatures, holding positions of an engineer, senior engineer, researcher, group leader, and deputy head of the Hadron Physics Department.
• In 1973–1975, took an active part in development of the world’s first frozen polarized target.
• In 1977, nominated by the Council of Young Scientists and Specialists for the Prize of the Central Committee of the All-Union Leninist Young Communist League.
• In 1993 and 1995, an international team of specialists from various institutes of Russia, Ukraine, and France under his leadership received INTAS grants for upgrading the MPT setup (previously used at Fermilab) and launching it for experiments Accelerator complex of the JINR.
• In 2000, successfully defended the dissertation for the degree of the Candidate of Engineering Sciences.
• Author and coauthor of over 150 papers.

Sector of Low Temperatures headed by Yuri Andreevich

• The cryostat was developed and constructed for a new polarized target of the Institute of Nuclear Physics in Mainz.
• In 2020, SLT specialists got engaged in development of a polarimeter for the polarized electron beam of MESA, a new superconducting accelerator at the University of Mainz.
• Several innovative projects, including a polarized-gas tomograph, were prepared.

With active participation of Yuri Andreevich

• a 60-cm³ frozen polarized proton target developed at JINR was successfully put into operation at IHEP in 1978. Now it has been upgraded for a new SPASCHARM project;
• a system for temperature measurements in cryostats of the ATLAS facility (liquid-argon calorimeter) was developed, and precision calibration of more than 700 platinum thermometers was successfully performed (under the JINR—CERN contract).

At present

• preparation for new polarization research at the VdG accelerator is underway at Charles University in Prague;
• investigations with polarized targets and beams in Protvino, Mainz, and Prague are united into the GDH&SPASCHARM&NN priority project (theme 03-2-1126-2010/2021) (Yu. A. Usov is one of the leaders);
• development of the cryostat for a new polarized target at the University of Bonn (ELSA accelerator) is coming to and end.
