Summary of current Road Map for future facilities

Introduction

EPS AachenJuly 19th, 2003

The current HEP programmeThere is an exciting running and approved HEP programme,ranging from precision physics on rare processesat low energies to the exploration of the energy frontier.

At low energy, LEAR is producing exciting physics from the first samples of antihydrogen; Brookhaven, CERN are measuring rare decays; Fermilab & CERN are measuring CP violation in kaons; DESY, JL and SLAC are looking atlepton scattering processes; SLAC & KEK are measuringCP violation and rare decays in B system.

Exciting results have been coming out for some time from theheavy-ion collisions at RHIC, complementing the lower-energyresults from CERN.

The current HEP programme

The exploration of the newly-established neutrino massparameters is a growth industry, involving KEK and a variety of reactor experiments, as well as a flourishing suite of astroparticle physics experiments also looking beyondneutrinos to dark matter etc. New facilities such as MINOS,CNGS and JHF are under construction.

At the energy frontier, Tevatron is now building up a head ofsteam in searching for new phenomena and t and b physics;HERA is emerging from the HERA II upgrade with an established new programme in EW spin physics and hopefully a major increase in integrated luminosity.

The LHC Project


5

The current HEP programme

The LHC detectors are now coming together and the LHCmachine has overcome problems with cable supply andis on schedule for first beam to the experiments in 2007.

This programme is both currently exciting and broad andpromises a very exciting future at LHC. However, with theexception of CERN, the programme of every high-energy laboratory in the world comes to an end around the end ofthis decade.

The Road MapECFA Working Group report (Sept. 2001) – (as an example)

Recommendations:

1) the allocation of all necessary resources to fully exploit theunique and pioneering LHC facility;2) continued support for ongoing experiments, since they promisesignificant scientific results, provide an optimal physicsreturn on previous investment, and are vital for the educationof young physicists;3) LC – see later4) an improved educational programme in the field ofaccelerator physics and increased support for accelerator R&D activity in European universities, national facilities and CERN.


7

The Road Map

ECFA Working Group report (Sept. 2001)Recommendations continued:For the long-term:5) a co-ordinated collaborative R&D effort to determine thefeasibility and practical design of a neutrino factory based on a high-intensity muon storage ring;6) a co-ordinated world-wide R&D effort to assess the feasibilityand estimate the cost of a 3-5 TeV e+e– linear collider (CLIC), a very large hadron collider (VLHC) and a muon collider; in particular, R&D for CLIC is well advanced and should bevigorously pursued.

The central role of CERN in Europe must continue …..


8

“The Consultative Group concurs with the world-wide consensus of the scientific community that a high-energy electron-positron linear collider is the next facility on the Road Map.”

“There should be a significant period of concurrent running of the LHC and the LC, requiring the LC to start operating before 2015. Given the long lead times for decision makingand for construction, consultations among interested countries should begin at a suitably-chosen time in the near future.”

The Road MapOECD GSF study group on particle physics report was released one year ago. Basically very supportive of this strategy.


9

Future machines - world situationThere is (unprecedented?) world-wide agreement that thenext step for accelerator-based particle physics should bethe construction, in a timely manner, of a linear e+-e- collider with an energy of at least around 500 GeV. ECFA report:“…the realisation, in as timely a fashion as possible, of a world-wide collaborationto construct a high-luminosity e+e- linear collider with an energy range up to atleast 400 GeV as the next accelerator project in particle physics; decisions concerning the chosen technology and the construction site for such a machine should be made soon;”

HEPAP report:“We recommend that the highest priority of the U.S. program be a high-energy,high-luminosity, electron-positron linear collider, wherever it isbuilt in the world…. We recommend that the United States prepare to bid to host the linear collider, in a facility that is international from the inception.”

ACFA: “ACFA urges the Japanese Government to arrange a preparatory budget for KEK to pursue an engineering design of the collider, to study site and civil engineering, as well as to investigate the process for the globalization.”


10

The Linear Collider

The publication of the TESLA TDR two yearsago precipitated the start of the “modern era” in LC.


11

The JLC TDR

We now have a second design on the table – the “JLC” – which is shortly to be renamed to emphasise its international character.

JLC TDR was presented in large symposium inKEK on 12th February, attended by ~400 peoplewith strong delegations from South Korea, India and China. Large number of talks; including from me and M. Tigner on view from Europe and US.

The Linear ColliderILCSC meets normally twice per year in conjunction withICFA Meetings. M. Tigner is chair of the ILCSC; BF chairs the ELCSG;Won Namkung chairs ALCSG;J. Dorfan chairs the North American equivalent. The major lab directors are members, including from Europe L. Maiani and A. Wagner. Additional members from three regions and also from RoW; other European memberis D. Miller.Accelerator subcommittee of ILCSC is directdescendant of “Greg Loew” panel, whose Review report wasaccepted by ICFA in February. Still needs to be broughtup to full strength by addition of missing expertise; shouldbe done in August.


14

The Linear Collider

A world-wide consensus has formed for a baseline LC project in which positrons collide with electrons at energies up to 500 GeV, with luminosity above 1034 cm-2s-1.

The energy should be upgradeable to about 1 TeV.

Above this firm baseline, several options are envisioned whose priority will depend upon the nature of the discoveries made at the LHC and in the initial LC operation.

http://sbhep1.physics.sunysb.edu/~grannis/wwlc_report.html

Consensus document agreed, based on TDRs and regional and OECD roadmaps:


15

The Linear ColliderILCSC has appointed a committee consisting of 6 people,two from each region, chaired by R. Heuer, to considerthe inputs from the regions as to the scope of the LC, whichwill form the input on which a decision on technology will be based. This decision will be made by a committee of “Wise Persons”,composed of senior and well respected members of thecommunity, mostly experimentalists but including sometheoreticians and possibly persons experienced in largeprojects from outside the community. Each region has beenasked to nominate four people, from whom three will be chosen, plus a chair, at the ILCSC meeting at LPS inAugust. The intention is for a technology choice to berecommended by this body to ILCSC & ICFA by mid-2004.ICFA has also recommended establishment of Global LinearCollider Centre, with regional “offices”.


16

ECFA/ELCSG activity

The subcommittee on Organisation under George Kalmusand the Accelerator group under Reinhard Brinkmann arewell established and working. The final part of the regionalstructure, the Outreach subcommittee has now also beensetup.

ELCSG has met nine times since it was formed just over ayear ago.

Members are BF (Chair), L. Maiani, A. Wagner, D. Miller,S. Bertolucci, F. Richard.


17

ECFA/ELCSG activity

The Executive has met twice and met with the ELCSG. Yesterday and today the first meeting of the extended committee has taken place. The committee is concentratingat first on addressing their message towards politicians andfunding autorities.

Outreach Subcommittee of ELCSG has an “Executive” offour members:P. Burrows (UK)G. Chiarelli (Italy)M. Kobel (Germany)F. LeDiberder (France)Each member of RECFA has been asked to supply the nameof a contact in their country who can serve on an extendedcommittee with one member per country.


18

ECFA/ELCSG activity

The committee has now concluded its businessand G. Kalmus has reported to ELCSG, RECFA and ECFAand last week presented the conclusions to the USregional workshop at Cornell. The final report should nowbe available from the ECFA web pages.

The subcommittee on organisation and management issuesfor the LC (SGOM) has had an intensive programme of meetings over the past six months, visited the major labs.and listened to a wide variety of evidence from both insideand outside the community – looking at models such asITER and ALMA, which are rather similar to the LC insize, complexity and scope.


19

ECFA/ELCSG activityOrganisation subcomittee membership:George Kalmus (Chair) (RAL)Peter von Handel (Secretary) (DESY)Umberto Dosselli (INFN)Lorenzo Foa (Pisa)Guy Wormser (IN2P3)Joel Feltesse (Saclay)Helmut Krech (ESRF)Ian Corbett (ESO)Chris Llewellyn Smith (Oxford)Eva Groniger Voss (CERN)Jos Engelen (NIKHEF)Kurt Hubner (CERN)Norman McCubbin (RAL)Torsten Akesson (CERN)


20

ECFA/ELCSG activityThe subcommittee recommends an organisation of limitedduration set up by international treaty, with “regional”governance, whereby the three regions can decide on theirown organisation but come together with an equal numberof delegates with equal voting power in the internationalproject. The host state should expect to pay a premium ofaround 25% of the project, the remainder of the costs beingdivided among the three regions equally. It is expected thatCERN will play an important role in the European region.

Similar exercises are going on in the other regions. ACFA’sreport already available and comes to proposals not dissimilar to Kalmus Committee. US committee should reportimminently.


21

The situation with thefunding authorities

The lead-up to the recent decision of the German government to support TESLA X-FEL showed that, at least in some governments, the LC is rising to the top of the agenda. Therehave certainly been detailed discussions within and betweenthe UK and German governments at ministerial level.

There are also reported to have been informal discussionsof LC issues at G8 science ministers’ meeting.

There is a clear need to broaden these discussions bothwithin Europe and internationally.


22

The situation with the funding authorities

A “pre-meeting” of representatives from Europe metin DESY in March and also held discussions with Dr.Marburger, the President’s Science Advisor. As a resultof this meeting, and after substantial discussion in OECDMegascience Forum CG II and at CERN Council, a“zeroth” meeting between European Funding Authoritiesand US will take place on July 29th/30th. The smallerEuropean countries will be represented by President of CERN Council and DG. Japan will not be represented at this meeting but intends to attend the next.

The meeting will be chaired by I. Halliday, CE of PPARC,UK. It will report back to GSF CGII, CERN Council etc.


23

OECD GSF CG2 meetingThe GSF CG has reconstituted itself and met in Paris inMarch. The major item on the agenda was the MinisterialMeeting of the GSF at OECD, which will take place at the end of January, 2004. We were reminded that the Ministers rarely made recommendations, but a previous one ~ “to investigate mechanisms to set up biodiversity programme”had turned out to be important as a spur when the detailednegotiations got tricky. We could benefit from a similardeclaration.A draft has been agreed by the GSF and will now be passedwith other papers to the meeting. The draft welcomes the CG Roadmap, recognises that the next pp project is the LC,the importance of global collaboration, of R&D and the prompt engagement of governments to further the project.


24

factoryThe recent excitement over physics, has brought to thefore questions related to producing them in ever larger numbers – the factory. All the regions, including ECFA,have active study groups.


25

factoryECFA report explicitly mentions in the Executivesummary recommendations:“a co-ordinated collaborative R&D effort to determine the feasibility and practical design of a neutrino factory based on a high-intensity muon storage ring”

ECFA report also explicitly recognises the importance and promise of the factory and supports the increase in resources and manpower in the field ofaccelerator physics necessary to build it:“A neutrino factory complex, beginning with its proton driver, allows a number of unique experiments in a fundamental domain: neutrino masses and mixing, CP violation, and lepton number violation. The realisation of this important programme requires a substantial international programme of R&D.”


26

factory

The HEPAP report is also very positive aboutthe required accelerator R&D. In case a LC is built in Europe or Asia it envisages:“A major new neutrino facility in the U.S., with significant international participation, as part of the worldwide neutrino program. The facility might becoupled with a new proton decay detector.”

ACFA relatively silent on factory: seems to be mostlyJapanese initiative. JHF Phase I, JHF to K, Hyper K is an ambitious & concrete programme that would be a major step towards factory.


27

factory

Substantial world-wide effort in R&D now accelerating.MICE proposal to study aspects of muon ionisation cooling, one of the most important aspects of the neutrinofactory concept. International collaboration has formedand proposal to carry out the work at RAL, UK, hasbeen submitted and passed international peer review.Substantial UK funds are in the process of being committed; more funding is required.

29

SummaryThere is unprecedented world-wide agreement that the next step in particle physics is the construction of a linear collider on an international basis to run concurrently with LHCInstitutions are being/have been set up world-wide to promote this concept and push towards agreement ontechnology and site in the shortest possible time.

For a variety of external factors, since the ECFA etc report, there has been a drop in accelerator R&D. ECFA are takinginitiatives with e.g. EU which hopefully can help to fill some of this gap.

Equally, all regions recognise the vital importance to thefuture of the field of accelerator R&D in general, and towardsthe factory in particular.

This also includes even longer-term goals, such as CLIC, VLHC, muon colliders, which will be vital for the futuresuccess of our field.
