	In the frame of the work, carried out at the Research Center of the Kurchatov Institute - IHEP on the development of four wide-aperture superconducting quadrupoles, a mathematical study of the mechanical behavior of the coil block of these magnets was carried out. The quadrupoles are intended for use in the magnetic final focusing system (FFS) of the ion beam in the experiments of the HED@FAIR collaboration. At the design stage of superconducting magnets, it is necessary to perform mathematical modeling to analyze the deformation of coil blocks during the assembly stages, cooling to operating temperature and the influence of ponderomotor forces. The results of computer simulation of changes in the geometry and distribution of forces in the coil block at all these stages are necessary to determine the value of the preliminary mechanical stress in the superconducting coil. The main results of numerical simulation of the mechanics of these magnets are presented in the article.

Beam-induced background comes from interactions of the beam and beam halo particles with either the residual gas in the vacuum chamber of accelerator or the collimators that define the beam aperture. Beam-induced processes can potentially be a significant source of background for physics analyses at the LHC. This contribution describes the simulation software environment used for this part of the CMS experiment activity and recent beam-induced background simulation results for the Phase-2 CMS operation design.
