3’000 fb-1
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.
LHC Draft schedule 2015
2015: Q1 & Q2 - preliminary
One thing we learnt from Run 1 – the schedule is flexible

Summary of the 2014 Evian workshop
Mike Lamont -
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”.

Physics Prospects at RUN 2
Run 2 physics program is well-defined
 Increase of cross sections from LHC8 to LHC13

Increase discovery potential at LHC
 Higgs factory
 5.5 M Higgs events produced
 100 K events useful for precision measurements
o Note: today ATLAS+CMS have 1400 Higgs events
 Higgs precision measurement
o Mass , JPC, BR, Cross section
o Measurements of Higgs couplings to fermions and bosons
 WLWL scattering at high E and Higgs self-couplings needs more lumi
 Search for SUSY or other BSM solutions
 SM measurements necessary to control systematics for above
 B-physics “window”
 high precision measurements
 Investigate possible “deviation” from SM predictions (mainly LHCb)

The Next to Next Future

INFN: WHAT”s Next (7-8 Aprile meeting di kick-off …ongoing)

EUROPA : Strategy Update Maggio 2013
U.S: P5 Report 22 Maggio 2014

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.

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.

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 and
continue the strong collaboration in the LHC with the phase-2
(HL-LHC) upgrades of the accelerator and both general-purpose
experiments (ATLAS and CMS). The LHC upgrades constitute
our 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?

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.

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.
