The Center for Integrative Quantum Beam Science (CIQuS) promotes "Cultivated Joint Usage" program that leads users to the multiple use of different quantum beams (multi-probe research) and supports them in three groups of analysis methods: surface structure, bulk structure, and heterogeneous structure. The CIQuS also promotes "Theme-driven Joint Research" in which staff members of the institute play a central role in setting up collaborative research programs that contribute to innovation, and solving problems through industry-university-government collaboration and international cooperation.
