Abstract—
To study collision processes of nuclei in the extracted beams of heavy ions of the NICA accelerator complex at the BM@N physical facility, a target with liquid hydrogen is needed. One important requirement for the experiment is the placement of the target directly on the boundary of the region of a uniform magnetic field of 1 T of the analyzing magnet SP-41. In connection with this requirement, a number of restrictions arise related to the operation of the GM cryocooler and systems of the cryogenic target in a magnetic field, as well as the effect of the elements of the target itself on the field uniformity. This paper provides a brief review of the literature on this issue and presents its own research on these issues: calculations and forecasts and options and methods for solving problems.
