Future of e+e- 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 R&D is aiming towards a proof
of feasibility for ~ 2010

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’

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

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/Orsay
7
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 @ RAL
 Presumably a JRA for FP7
F. Richard LAL/Orsay

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…

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…
- 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

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

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/Orsay
12
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
