F. Richard LAL/Orsay 1 ELAN in 2006 Annual Meeting

F. Richard LAL/Orsay2 Main Activities  Future e+e- LC: European and International efforts European and International efforts  New techniques of acceleration: the start of EUROLEAP at the Orsay meeting  ELAN workshops  ELAN dissemination  ELAN and FP7

F. Richard LAL/Orsay3 Future of e+e- colliders The context: The context:  ILC, the worldwide project for a TeV collider will be using the SCRF technology developed in Europe with a central facility in DESY. European funding should continue playing a major role in this effort  This project is the post-LHC priority of HEP and a major effort has been started called the GDE to achieve costing on machine and detectors  In Europe, CLIC R&D is aiming towards a proof of feasibility for ~ 2010

F. Richard LAL/Orsay4 In the US  P5 Report: The Particle Physics Roadmap October 2006  Quote:  ‘The ILC is the highest priority future project in the recent EPP2010 report from the National Research Council. We allocate $500 million for the relevant R&D activities over a five-year period. The goal is to produce a technical design on an international basis and once initial LHC physics results are known to initiate the next step toward realization of this accelerator’

6 Europe  Priority is for LHC while, as noted by ESFRI, a strategy group created by CERN council claims that:  ‘It is fundamental to complement the results of the LHC with measurements at a linear collider. In the energy range of 0.5 to 1 TeV, the ILC, based on SC technology, will provide a unique scientific opportunity at the precision frontier’  ESFRI notes that ‘It is also vital to strengthen the advanced accelerator R&D programme’  CERN while participating actively to the ILC GDE is coordinating the R&D effort on CLIC, the future Multi TeV LC

F. Richard LAL/Orsay7 ELAN and LC  ELAN is directly connected to ILC: 3 WP leaders (BDYN, INSTR, SCRF) belong to the GDE  ELAN is supporting or organizing Workshops around ILC and CTF  ELAN is encouraging synergies between ILC and CLIC:  Preparation of an experiment at KeK on µbeams (metrology/alignment)  Beam Dynamics  Laser technology to produce polarized e+

F. Richard LAL/Orsay8 Generation of polarized e+  Previous Workshop has been summarized on CARE/ELAN document (CERN, Japan, Fr, It, Ge, Rus, China…) (CERN, Japan, Fr, It, Ge, Rus, China…)  Ideas are rapidly evolving (ERL scheme avoiding e+ ring, improving on FB cavities) proposed end of RAL proposed end of RAL  Presumably a JRA for FP7

F. Richard LAL/Orsay9 Future techniques of acceleration  Recent improvement achieved: W. Leemans et al. in Nature Sept 2006 (S.M. Hooker from ELAN)  1 GeV/cm with 2.5% 30 pc 1.6 mrad with a 40 TW laser 40 TW laser  In Europe there is also progress (cf V. Malka) and EUROLEAP (NEST) initiative has been launched during the ELAN WS in Orsay  It includes synergy with accelerator experts  A possible roadmap for multi-TeV colliders ? At least for XFEL…

F. Richard LAL/Orsay10 Electron Accelerator R&D for the Energy Frontier  CARE/ELAN on May 15: - Plenary in the morning on laser/plasma, a proposal for a new infrastructure on SC, Progress in CLIC cavities, BDYN+INSTR… - Plenary in the morning on laser/plasma, a proposal for a new infrastructure on SC, Progress in CLIC cavities, BDYN+INSTR… - FP7 1h30 discussion in the afternoon followed - FP7 1h30 discussion in the afternoon followed by a working party (ELAN Doc ) by a working party (ELAN Doc ) - 4 Parallel ELAN sessions for 3h Parallel ELAN sessions for 3h30  EUROLEAP kick-off meeting on May 16  In // EUROTEV on May 16  Conclusions May 17

F. Richard LAL/Orsay11 FP7  3 possible tools to prolong CARE and EUROTEV  CNI new tool which requires ESFRI support (~OK for CERN but only implicit)  DS very different from EUROTEV <5M€  JRA within I3 with TA and NW <45M€  Very large set of LoI presented to ESGARD amounting to a very large amount of money

F. Richard LAL/Orsay12 ELAN & FP7  ESGARD has split in 3 the relevant LoI  ELAN is involved in the organization of 2 of them and on the CNI  CNI : SCRF see talk W. Weingarten  IA on SC RF  IA on new techniques of acceleration which include CLIC and laser/plasma R&D  These as well as the ELI CNI have been discussed within ELAN in parallel sessions at this meeting

F. Richard LAL/Orsay13 Dissemination in ELAN  10 workshops + 1 Accelerator school were supported  ELAN annual WS was held in Orsay with 85 participants  This effort resulted in 16 ELAN Documents and 2 ELAN-Conf and 2 ELAN-Conf  The ELAN web page contains infos about the workshops and about the documents
