The Alignment Conditions Technology Group is core-oriented to provide full-chain technical support for ion accelerators and related major facilities of IMP. Its work covers the design, implementation and full-lifecycle operation and maintenance of ion accelerator alignment measurement, circulating cooling water systems, ventilation and air conditioning systems, and compressed air systems, ensuring the stable and efficient operation of facilities with precise technologies.

Deeply engaged in the field of major scientific and technological infrastructure, the group participates in the research, development, construction, operation and maintenance of a number of national-level facilities. Its core tasks cover three major areas: first, undertaking the daily operation and maintenance of the Heavy Ion Research Facility in Lanzhou (HIRFL) to consolidate the foundation for the stable operation of existing facilities; second, deeply participating in the construction of new major facilities, having successively undertaken the full-process design, installation and commissioning of alignment measurement, circulating cooling water, ventilation and air conditioning, and compressed air systems for the 300MeV proton-heavy ion accelerator of the Space Environment Simulation and Research Infrastructure (SESRI), the Proton Radiation Effects Facility (PREF), and the High Intensity heavy-ion Accelerator Facility (HIAF); third, actively promoting the scenario-based application of cutting-edge technologies such as digital twin modeling and intelligent alignment in major scientific and technological infrastructure, and continuously carrying out key technological research and discipline system construction to provide core impetus for technological upgrading and talent training in the field.
