“Linear collider studies: This heading includes the total funding for CTF3, the CLIC study and the CLIC/ILC collaboration as well as the CERN’s participation in the specific detector R&D for a future linear collider. Compared to last year’s MTP, the materials heading is reduced with 10 MCHF, which is implemented as a shortening of the study by around one year, as part of the overall need to limit the cumulative budget deficit.” “Future Circular Collider study: this heading covers all studies for high-energy circular colliders in time for the next update of the European Strategy for Particle Physics by 2018/2019. It also includes an elaboration of the physics cases, detector concepts for all three types of collider (hadron, lepton and lepton-hadron), as well as the conception of staging and implementation scenarios. Compared to last year’s MTP, the materials heading is adjusted downwards with 1MCHF per year (and 2 MCHF in 2016), as part of the overall need to limit he cumulative budget deficit.” “It should be emphasised that a choice between CLIC and FCC will have to be made at the latest by the time of the next update of the European Strategy for Particle Physics around 2018-2019 in order for the next large-scale facility to embark upon the corresponding project phase. For this reason, as of 2020 the CLIC and FCC activities are merged under a single heading in this MTP.”

Resources/planning - MPT

From the MTP: In CERN 2015-19 budget planning LC activities reduced by ~20% with respect to last years budget estimates

Have implemented these changes in planning for coming year, aiming to reduce most significantly in 2018-19, still providing the necessary input to the European Strategy Update

Keeping in mind: many commitments (~60) related to Xband structure and testing plus the CTF3 programme in the years 2015-2017, easing up somewhat in 2018-19. These commitments are covered by numerous R&D contracts and MoU annexes covering personnel and hardware, exchange/test of equipment being built in the collaboration, and around 80 ph.d students in action.Will review/update this programme/goals during the autumn, specific review in October 13 and LCWS 2015 in Whistler

Other interactions with management: The fact that CTF3 is closed down by end 2016, and there is no overall LC planning or activity foreseen at CERN after 2018 is a significant concern for the collaboration. See CALIFES talk later.

Resources/planning – consequences

Goals 2018

1. Summary project plan document (physics, machine parameters, cost, power, site, staging, construction schedule, brief summary of main tech. issues, prep. phase (2019-2025) summary (see point2 below), detector studies (document 50-80p) – plus short versions

2. Preparation phase plan document (critical parameters, status and next steps 2019-2025 - what is needed before project construction start up, strategy, risks and how to address them, inside and outside CERN, in industry (document)

3. Detailed documentation across project: EDMS/WBS based (exists but need update, already used for cost, power), review and improve. Use by 2018 for consistent technical documentation, tender/commercial documents (protected), results, notes/publication for each WP and/or activity.

4. Techno transfer/spin-off paper including training (ph.d and fellows) (can be done earlier)

5. Comprehensive physics and detector documentation (part of which will be summarized in document 1 above). Summary several paper planned in the period 2015-2018 covering physics topics, detector studies and R&D.
