Title: News from TESLA LC

News from TESLA LC
Recommendation by the German Science
Council Technical developments Organisation of
the community Management proposal for the project
WR-Recommendation concerning the X-FEL
The German Science council has converted its
statement on 14 November into a recommendation.
  • The Science Council requests the Federal
    Government to give its binding consent to German
    participation in the LC as soon as possible after
    the project proposal has been submitted with
    specific details concerning international funding
    and international cooperation.

The Science Council requests the Federal
Government to give its binding consent to German
participation in the TESLA X-FEL project as soon
as possible after the revised project proposal
has been submitted .
DESY has answered on 24 October to the SC.

Cooperation with SLAC on FEL
MoU between DESY and SLAC on a close
collaboration in X-ray laser research, to make
joint efforts to promote this trend-setting field
of research Collaborative Research Effort to
Enable the Exploitation of the Scientific
Capabilities of the Linac Coherent Light Source
(SLAC project LCLS)and the TESLA X-Ray
Free-Electron Laser . The Memorandum was signed
on Friday, November 1, in the Department of
Energy (DOE)in Washington The MoU specifies the
exchange of personnel, equipment, research
results and data, as well as know-how.This will
accelerate and contribute to the scientific
programs of both facilities, which complement one
another in their qualities.
Status and Next Steps
The North German Science ministers have given
TESLA officially their backing. The SC regards
the funding of facilities of this size as
continuous process Public discussion has started
(DPG meeting, KET) Thus it considers the
recommendation to be the basis for further
necessary discussions on support The SC will
submit concrete recommendations on the priorities
for implementation, which take into account the
science policy debate on the goals and funding of
the facilities Political decision expected in
The TESLA Collaboration
  • The TESLA Collaboration has grown further
  • - 44 Institutes in 12 countries, Spain has

The Way to 35 MV/m and 800 GeV
  • Improvement of surface quality with

Single cell cavities, EP
800 GeV goal
40 MV/m
CERN/KEK/Saclay/DESY collaboration
Transition from single-cell results to multi-cell
results has again been successful
Site Planning Status
We prepare to start the legal procedure required
for an implementation at the site in a few
months, as part of the overall feasibility study

work out possible models for the design,
construction and operation of a linear collider

road map towards setting up the project This
refers specifically to a 0.5 to 1.0 TeV
electron-positron machine with a latest
completion date of 2014.

Organisation and Management
  • The proposed organisational and management
    structure of the TESLA Project is based on the
    concept that
  • the responsibility for most subsystems is
    shared between different institutions and even
    regions, in order to exploit best the know-how
    available around the globe.
  • The same principle is being implemented for ALMA.

A specific proposal has recently been submitted
to the German Science Council

  • Remote operation will very likely be of key
    importance for the future operation of large
  • Key issues
  • social aspects
  • Tests in this area are ongoing or planned (TTF,
    A0, LINX, PI3)

ICFA is considering to sponsor future GAN
OECD Consultative Group
OECD Consultative Group
... Discussion on organisational issues etc It
was decided to continue these OECD discussions..
Continuation of CG
  • GSF felt that Consultative Group (CG) should
    continue in a form to be decided by the
    interested countries
  • UK should continue to be the lead country
  • Non-OECD representatives must be invited
  • Majority of CG work related to LC
  • Next meeting of GSF in Jan 03, proposal of
    charter by CG should then be available
  • Meeting of QECD science ministers in early 2004
  • Therefore Meeting of CG March/April 03 and Nov

New ECFA Study on Physics and Detectors for a LC
  • The organising committee of the Extended
    ECFA/DESY Study proposes that ECFA should support
    these activities for a further two years, from
    Spring 2003.
  • The ILCSC is relying on the studies in the three
    regions to provide input on Physics and
    Detectors. Both the USA and Asia plan continued
  • The present ECFA/DESY Study involves a widely
    distributed group of experimenters and theorists
    doing feasibility studies, fundamental
    calculations and RD.
  • The study will help the momentum of this work in
    Europe to be kept up to maintain contributions to
    the formation of an international user community.
  • The present study comes to an end with its
    workshop in Amsterdam, 1-4 April 2003. ECFA is
    asked to approve the new Study at their November
    2002 plenary meeting.

  • The Science Council has evaluated TESLA with its
    two goals very favourably and made a positive
    recommendation last week.
  • The homework as asked for has been made
  • The technical progress continues, the Technical
    Review was very helpful and positive for TESLA,
    in spite the fierce competitive atmosphere
  • Organisational aspects are being addressed
  • The community is organising itself
  • The political discussions have started
