ESU 2013: “CERN should undertake design studies for accelerator projects in a global context, with emphasis on proton-proton and electron- positron high-energy frontier machines.”

Project

FCC Study : p-p towards 100 TeVKick-off meeting: 12-15 Feb. 2014

CDR and Cost Review 2018


Future Circular Collider Study - SCOPE CDR and cost review for the next ESU (2018)

Forming an international collaboration to study: • pp-collider (FCC-hh)

defining infrastructure requirements

• e+e- collider (FCC-ee) as potential intermediate step

• p-e (FCC-he) option• 80-100 km infrastructure

in Geneva area

~16 T 100 TeV pp in 100 km~20 T 100 TeV pp in 80 km


≈330 participants

6Future Circular Collider StudyFCC Kick-Off 2014

• Push the energy frontier beyond LHC• High Priority item within the European

Strategy for Particle Physics • Timely

lead times for R&D very longLHC physics program for ~20 years

• Need for a project plan when LHC results indicate direction to go

Why

Rolf Heuer – kick-off meeting


• Technical/Conceptual Design Reports for linear e+e- Colliders exist: ILC/CLIC

Japan interested in housing ILC Europe and CERN: participation in both endeavours will be continued• Need to go beyond present energy frontier

circular high energy collider

What



• Exploitation of all options for such a project (hh – ee – ep) within one study

• Global Collaboration for the Study of Future Circular Colliders

(similar to the CLIC collaboration)• Hosted by CERN

How



High-energy hadron collider FCC-hh as long-term goal• Seems only approach to get to 100 TeV range in the coming decades • High energy and luminosity at affordable power consumption• Lead time design & construction > 20 years (LHC study started 1983!)

Must start studying now to be ready for 2035/2040

FCC motivation: pushing energy frontier

Lepton collider FCC-ee as potential intermediate step • Would provide/share part of infrastructure• Important precision measurements indicating the energy scale at which

new physics is expected• Search for new physics in rare decays of Z, W, H, t and rare processes

Lepton-hadron collider FCC-he as option • High precision deep inelastic scattering and Higgs physics

Most aspects of collider designs and R&D non-site specific.Tunnel and site study in Geneva area as ESU requests.

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.


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.


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.
