The foreseen strategic R&D described in this document focuses on those technologies and fields of expertise that will be crucial for any future experiments in particle physics and in which CERN groups have significant if not unique expertise. In analogy with the importance of the development of high field magnets and high gradient accelerating structures for future accelerators, we have identified key technologies and indispensable expertise without which future experiments cannot be built.
The results of this R&D will be building blocks, demonstrators and prototypes, which will form the technological basis for new experiments and experiment upgrades beyond the LHC Phase-II upgrades scheduled for the long shutdown LS3.
