A large number of advanced accelerator concepts are in its design and construction phase in recent years, such as SPIRAL2, XFEL, CLIC/ILC, LHC-upgrade etc. At the same time of development of high power and high intensity machines for fundamental researches, application of accelerator technologies takes an important role to fulfil the social requirements for future world, such as accelerator-driven system (ADS) for transmuting radioactive waste, ion accelerator for advanced cancer therapy. In both cases, it is required to put a high importance on developing specific knowledge in the field of beam dynamics as well as beam-material / field-material interactions. This is because operational reliabilities of accelerator beams depend strongly on the material behaviour in extreme conditions in such machines. Prospective phenomena on metal surfaces under extreme conditions have been found as limiting factors of the accurate, reliable and long lifetime operation. One has to overcome those phenomena in order to achieve its severe qualifications. However, such phenomena for example vacuum discharges in RF components are not yet well understood. In this talk, I will present R&D activities on material interactions in accelerators at CERN for CLIC study. And I will explore the possibility of applying those activities to the projects of the LPSC accelerator group.
