JINR Youth Grants 2021: Ivan Gorodnov
— Ivan, could you please tell us a little about yourself.
— I graduated from the Moscow Power Engineering Institute, specializing in "Physics and Technology of Low Temperatures", and I am currently working on my postgraduate thesis there.
My area of interest is polarization physics. More specifically, it is polarized frozen targets. Together with my colleagues from the DLNP Sector of Low Temperatures, we develop, design, and manufacture such targets, as well as operate them during experiments. Our sector is one of the world leaders in this field.
Currently, I am involved in polarization experiments conducted by the Sector of Low Temperatures using our in-house manufactured targets in three projects: CB-ELSA (Bonn, Germany), A2 (Mainz, Germany), and SPASCHARM (Protvino).
The main and most complex component of polarized targets is the cryostat for dissolving Helium-3 in Helium-4. My work at the Joint Institute for Nuclear Research began in 2014 precisely with the manufacturing of such a cryostat.
At the Sector of Low Temperatures, I am glad to be engaged in work that is interesting for me and closely related to my studies.
— Which projects and tasks from the past and current year did you include in your grant application?
— The grant application included conducting tests and commissioning a cryostat for a frozen-spin polarized target at the University of Bonn, which is being created under a contract. Covid-19 restrictions have significantly shifted our planned business trips to Bonn. Nevertheless, we expect to complete this work in November-December of this year. Combined with the upcoming trip to Bonn, the total duration of data-taking sessions will be 13 weeks.
Our target is also a part of the setup in Protvino. Unfortunately, due to intensified restrictions in October, the work there has been postponed until next year.
In 2020, two major publications on previously conducted experiments were published with our participation.
We have signed a contract and begun work on the joint creation of a new polarized target for the University of Mainz. The first components of the target have already been manufactured.
— How do you assess the preliminary results of the grant work for 2021?
— A substantial work has been done.
Overall, the set tasks have either been completed or will be completed before the New Year during the upcoming trip to the University of Bonn. The business trip will last 45 days, and we plan to complete testing of the new cryostat for the university. Experiments on the existing setup in Bonn will also be finished.
Unfortunately, the work in Protvino has been postponed for reasons beyond our control.
— Do you plan to apply for a grant in 2022?
— Yes, I do. Plans for 2022 include conducting experimental runs in Germany and Protvino, as well as manufacturing major components of the new target for Mainz.
Thank you, Ivan, for the interview, and we wish you further success in your work and research!
