The past: RUN 1 The luminosity has reached a value of 7.7x1033 cm-2s-1, The collision energy has reached 8 TeV in 2012.

The present: LS1 Superconducting interconnections have been upgraded to avoid electrical faults (19 Sptember 2008) There are 10,000 "splices” superconducting connections between magnets on the LHC. Each splice carries 13,000 amps.An additional piece a "shunt” has been added to each splice. A total of 27,000 shunts have been installed in the 27-kilometre accelerator.

The next future: RUN2 Running will resume in 2015 (20 month shutdown) with increased collision energy of 13 TeV and another increase in luminosity

Run 2 is currently planned for 2015-2017, 2015 will involve starting up the machine at a new energy and collision rate, and so a lot of time in 2015 will be spent on making the machine work properly and efficiently.Most of the data in the next run will appear in 2016-2017.

Experiments• See 2015 as a commissioning year and an

investment– 25 ns very strongly favored– Will accept up to 1 fb-1 @ 50 ns

• Target energy by the end of summer 14– 6.5 TeV is target (and the maximum)– Will only be confirmed at end of powering tests

• Peak mean pile-up of around 50 “is considered to be acceptable”.

INFN: WHAT”s Next (7-8 Aprile meeting di kick-off …ongoing) CSN1: LTS1 Workshop 22-24 Maggio La BiodolaEUROPA : Strategy Update Maggio 2013U.S: P5 Report 22 Maggio 2014

GIAPPONE: ILC Japan is proceeding on a bid to host ILC . International negotiation for the next 3-5 (?) years

CINA : FCC 100 TeV machine -80 100 Km circumference Future Circular Collider

Workshop on the Long Term Strategy of INFN-CSN1: the next ten year of accelerator-based experiments

– The goal of this workshop is the development of a strategic plan for the CSN1 to be executed over the next 10-year timescale, in the context of a 20-year global vision for the field. The plan should identify clear scientific priorities, while taking into account technical readiness and financial feasibility of the potential new activities and infrastructures. The unique aspects of the science achievable with accelerator based experiments relative to other approaches should also be emphasized.

– This event is an integral part of the INFN "What's Next" process started with the kick-off meeting held in Rome on April 7-8, 2014.

– Documento (White Paper) in preparazione

CSN1 strategy workshop, Elba, Maggio 2014 F. Bedeschi, INFN-Pisa 12

European Context

• EU strategy update May 2013– Europe’s top priority should be the exploitation of the full potential

of the LHC, including the high-luminosity upgrade.– CERN should undertake design studies for accelerator projects in a

global context, with emphasis on proton-proton and electron-positron high-energy frontier machines.

• high-field magnets and high-gradient accelerating structures

– Europe looks forward to a proposal from Japan to discuss a possible participation.

– Experiments in Europe with unique reach should be supported, as well as participation in experiments in other regions of the world.

CSN1 strategy workshop, Elba, Maggio 2014 F. Bedeschi, INFN-Pisa 13

An updated strategic plan for the U.S that can be executed in a ten-year timescale, in the context of a twenty-year global vision for the field.

Recommendation 10 : Complete the LHC phase-1 upgrades andcontinue the strong collaboration in the LHC with the phase-2(HL-LHC) upgrades of the accelerator and both general-purposeexperiments (ATLAS and CMS). The LHC upgrades constituteour highest-priority near-term large project.

The charge calls for planning under two specific budget Scenarios, reflecting current fiscal realities, as well as for an additional unconstrained Scenario.

INFN Current activities evolution: LHC

• Large INFN involvement ~ 500 FTE/ 60% of CSN1 budget:– ATLAS/CMS: Phase 1 fully funded and in progress– ATLAS/CMS: Phase 2 R&D funded & starting– ATLAS/CMS: Phase 2 upgrades under discussion

• Logical continuation for INFN-LHC community• Strong physics case• Strong international support in Europe, US and Japan• Construction: 2018 – 2025, data: 2026-2035

– A long way to get to 3000 fb-1 ..... Is it sustainable?– Does TOTEM makes still sense after completion run2 ... (3)?

– LHCb: • Upgrade approved by INFN• Construction: now – 2019, data: 2020 - > 2028 ???

– How long can it really last? How far can we push flavor physics at LHC?– Where does the community go?

LHCb upgrade (Phase 1) Cronologia eventi rilevanti CSN1

• Approvazione Scientifica del progetto in CSN1: giugno 2013 – 5.560 ME

• CSN1 alloca, per 2014, 589.5 kE s.j all’approvazione CTS : Settembre 2013

• Parere di congruita` espresso dal CTS : Dicembre 2013– CTS believes that the explanations provided by the Collaboration in response to CTS requests have been

entirely satisfactory and therefore it recommends the project for the approval.

– The only warning the Council gives is that the project is recommended on condition that other major Funding Agencies (CERN, France, Germany, Netherlands, Russia, Switzerland, UK, US) involved in the upgrade, will also agree to finance it.

• Approvazione CD 29 Gennaio 2014• Review progetto da parte dei referee 19-20 Marzo 2014• Referee Status Report : 9 Aprile 2014• Programmazione e richiesta sblocchi : Maggio 2014

CMS upgrade (Phase 2)

• INFN garantisce un finanziamento specifico per l' R&D fase2 articolato su 3 anni e fino ad un massimo di 2.2 MEu.

• La gestione di questi fondi avverrà tramite una sigla dedicata RD_FASE2 che raccoglie tutte le attività presentate e analizzate dai referees.

• Temporaneamente i finanziamenti associati a RD_FASE2 sono gestiti dai responsabili nazionali di ATLAS e CMS, ma nel corso della riunione di settembre di CSN1 verra' discussa e finalizzata la struttura di responsabilita’ finale.

In order to further increase its discovery potential beyond 2020, LHC would need an upgrade to increase the total number of collisions by a factor of 10.

a number of innovative technologies to be explored 11-13T superconducting magnets, Compact/ultraprecise superconducting radio-frequency cavities for beam rotation 300-m-long, high-power superconducting links with zero energy dissipation.

new demands on vacuum, cryogenics and machine protection, and will require new concepts for collimation and diagnostics, advanced modelling for the intense beam and novel schemes of beam crossing to maximize the physics output of the collisions.
