14 H2020 FCC DS proposal Michael Benedikt ESGARD Meeting 24 March 2014 Scope H2020 FCC proposal Main aim of the FCC study is to provide a complete conceptual design report (CDR) by 2018, as input for the next European Strategy Update. The H2020 Design Study proposal will comprise a subset of FCC work packages which require international collaboration and the technical expertise from several partner institutes, and which have potentials for innovation and scientific impact. The H2020 FCC DS will address key questions concerning the technical and financial feasibility. In the frame of the H2020 FCC DS various design alternatives will be analysed, with regard to both accelerator configuration and the underlying technologies, in terms of relative merits and relative cost. H2020 FCC DS assumed to start Q1/15 and run for 4 years until Q4/18.

15 H2020 FCC DS proposal Michael Benedikt ESGARD Meeting 24 March 2014 Main activities The H2020 FCC DS activities will include parameter optimization, optics design and beam dynamics studies, for all collider scenarios considered; civil engineering and technical infrastructure concepts; development of technologies such as high-field magnets, SRF systems, highly efficient RF power sources, as well as other specific technologies, including some prototyping. Implementation concepts for industrial production will also be studied. The H2020 FCC Design Study will provide essential input for the next update of the European Strategy for Particle Physics, enabling Europe to define its future roadmap and to strengthen its world-leading position in high-energy physics. The H2020 FCC DS will also study options for the governance structure of the future global project, along with staging and implementation scenarios.

16 H2020 FCC DS proposal Michael Benedikt ESGARD Meeting 24 March 2014 Impact H2020 FCC proposal Responding to the request formulated by the 2013 European Strategy Update, the FCC and H2020 FCC design studies will deliver a CDR, including cost model and performance estimates, for future energy- frontier circular collider options. This CDR will provide a sound decision basis for establishing the long-range plan and future roadmap in high- energy physics. The work carried out within the H2020 FCC DS will further strengthen Europe’s leadership position, attracting scientific and technical contributions by scientists from all over the world. Through collaboration with industrial partners in the areas of key- enabling technologies, the development of innovative solutions by European industries is expected. Such solutions will be essential for achieving the optimum scientific performance.
