CERN important events Restart of the LHC

CERN: important events • Restart of the LHC: – First beam on 20 November at 0. 45 Te. V – First collisions on 23 November, followed by slowly ramping up the beam energy to 1. 18 Te. V (= world record), corresponding to 2000 A – Collisions until 16 December; now: technical shut-down until Feb. – Cost for repair: 40 MCHF (without accompanying measures) • DG’s future plans: – A lot of consolidation needed (spares, He storage, cooling/electricity maintenance, tunnel overpressure requirements, busbar splices, etc) = 25 MCHF/year over approx. 4 -5 years – Long-term outlook on LHC exploitation developed in the Chamonix workshop will go via SPC to Council in June – Possible change of operation mode to a bi-annual shut-down • Evolution of LHC: “Install new items when they are needed” – LHC upgrade (“Phase I”) (inner triplets, LINAC 4) not before 2016 – S-LHC (“Phase II”) (luminosity x 10, PS 2, SPL) likely in the 2020 ies.

CERN: Report from Council (1) • Council – elects Prof. Michel Spiro (FR) as President – extends the FC Chair Martin Steinacher (CH) for another year – notes that none of the large non-member States (Brazil, Canada, India, Japan, Russia, USA, Korea) wants to become a full member. Brazil and India are looking into Associate Membership (provided the contributions are small enough…) – agrees to start at an informal level the technical verification process for the five applications received (Cyprus, Israel, Serbia, Slovenia, Turkey); decision re applications will be taken later on the basis of the work of the WG Enlargement – notes the CERN Pension Fund situation, where 2’ 100 MCHF are missing (structural deficit aggravated by the financial crisis in 2008). Some 80 MCHF per year are needed over a period of 30 years to improve the situation.

CERN: Report from Council (2) Council agrees • on the guidelines for geographical enlargement • consensus on the principle of global opening of the Organization • the concrete paths towards global opening need to be examined further • the current Associate Status should be revised with a view to greater flexibility, balancing obligations and benefits • the relationship between the status of Candidate for Accession to CERN and the status of Associate Membership is to be discussed; • other options for participation in the Organization's activities will be streamlined (Observer Status, Co-op Agreements, etc) • to use the LHC upgrade as a test-bed for a global collaboration project („stakeholder model“, similar to the LHC experiments: RRB, maintenance and operation aspects) • to decouple the scientific enlargement from the geographical enlargement Next European Strategy update 2012?
