ELAN in 2006

ELAN in 2006

• Annual Meeting

2
Main Activities

• Future ee- LC
• European and International efforts
• New techniques of acceleration the start of
  EUROLEAP at the Orsay meeting
• ELAN workshops
• ELAN dissemination
• ELAN and FP7

3
Future of ee- colliders

• The context
• ILC, the worldwide project for a 0.5-1 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 RD is aiming towards a proof of
  feasibility for 2010

4
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 RD 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

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 RD programme
• CERN while participating actively to the ILC GDE
  is coordinating the RD effort on CLIC, the
  future Multi TeV LC

7
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

8
Generation of polarized e

• Previous Workshop has been summarized on
  CARE/ELAN document-2006-006
• (CERN, Japan, Fr, It, Ge, Rus, China)
• Ideas are rapidly evolving (ERL scheme avoiding
  e ring, improving on FB cavities)
• proposed end of September _at_ RAL
• Presumably a JRA for FP7

9
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
• 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

10
Electron Accelerator RD 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, BDYNINSTR
• - FP7 1h30 discussion in the afternoon
  followed
• by a working party (ELAN Doc. 2006-04)
• - 4 Parallel ELAN sessions for 3h30
• EUROLEAP kick-off meeting on May 16
• In // EUROTEV on May 16
• Conclusions May 17

11
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 lt5M
• JRA within I3 with TA and NW lt45M
• Very large set of LoI presented to ESGARD
  amounting to a very large amount of money

12
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 RD
• These as well as the ELI CNI have been discussed
  within ELAN in parallel sessions at this meeting

13
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
• The ELAN web page contains infos about the
  workshops and about the documents

Conclusions

• Very active period on electron accelerator RD
• Successful ELAN workshop at Orsay
• ELAN is a useful tool in
• - Supporting workshops on future linear
  colliders
• - Promoting new techniques for acceleration
• - Preparing for FP7
