These ideas were submitted to the BMBF, MES and the Presidium of the National Academy of Sciences of Ukraine and received favorable approval. In the framework of a specific implementation of the practice of remote experiments, the following is done. 1. The priority directions of further joint works and technical requirements for experimental designs are determined. In particular, four directions were identified: ion irradiation of superconducting samples in order to improve their transport and superconducting properties, measure the mass of vortices of magnetic flux in superconductors, develop new Josephson transitions for superconducting computers, and study the topological effects in magnetic films. 2. Three types of samples, iron-based superconductors, the most promising for increasing the temperature of the superconducting transition and other superconducting characteristics by ion implantation have been identified. It is established that for FeSe (system "11"), one can expect an increase in Tc in the implantation of both anions and cations, in order to increase Tc in Ba(Fe,Co)2As2 (BFCA), it is most expedient to use cations, elements of the 1st group such as Li, Na, K, Cs, Rb, and for KFe2As2 (KFA) more promising is irradiation by anions, to increase the concentration of holes. 3. Preliminary simulation has confirmed that lighter elements cause less damage to the crystalline lattice and penetrate deeper into specimens, define penetration and destruction profiles, and are selected as the main elements for cationic implantation of lithium, and for anionic - fluorine at energies of 200 kV and doses up to 1 At%.
