Goals of the Study

The goals of the extended Study are:
  1. to continue to build up the active community of experimenters, theorists and machine physicists who prepared the TDR, to be ready by 2003 to make firm proposals for a funded programme of linear e+e- physics up to about 1 TeV, if it is decided to go ahead.
  2. to complete and extend feasibility studies on important physics channels.
  3. to review the detector design in the light of results of the R&D programmes which are now getting under way.
  4. to interact with the accelerator designers on questions relating to the machine/detector interface, including backgrounds, shielding, radiation levels, beam position monitoring, luminosity measurement and energy measurement.
  5. to look at the physics potential and the technical possibilities for extensions of the programme to produce real photon-photon, electron-photon and e-e- collisions.
  6. to extend the work of the "LoopVerein", developing new tools and techniques for calculating precise rates for Standard Model and supersymmetric processes that match the expected experimental precision.
  7. to continue and extend contacts with physicists in North America, Asia and throughout the world. Wherever the collider is built the collaborations doing the experiments are likely to be composed of groups from all over the world - as they were at LEP and are at HERA, the Tevatron and the LHC.

Linear Collider Study Extended by ECFA


A strong physics case has been made for building an e+e- linear collider with an energy range from 90 GeV up to about 1 TeV. It was presented on March 23/24 at the TESLA Colloquium at DESY TESLA Colloquium at DESY and is documented -- along with a detector design - in the third volume of the TESLA Technical Design Report (the "TDR", report DESY 2001-011, ECFA 2001-209). That volume, and the detailed supporting notes that go with it, were produced by members of the Second ECFA/DESY Study of Physics and Detectors for a Future e+e- Collider , drawing on contributions from physicists throughout Europe and around the World. Now the mandate to the Study from ECFA (the European Committee for Future Accelerators) has been extended for another two years to Spring 2003.

The goals of the extended Study are:

  1. to continue to build up the active community of experimenters, theorists and machine physicists who prepared the TDR, to be ready by 2003 to make firm proposals for a funded programme of linear e+e- physics up to about 1 TeV, if it is decided to go ahead.
  2. to complete and extend feasibility studies on important physics channels.
  3. to review the detector design in the light of results of the R&D programmes which are now getting under way.
  4. to interact with the accelerator designers on questions relating to the machine/detector interface, including backgrounds, shielding, radiation levels, beam position monitoring, luminosity measurement and energy measurement.
  5. to look at the physics potential and the technical possibilities for extensions of the programme to produce real photon-photon, electron-photon and e-e- collisions.
  6. to extend the work of the "LoopVerein", developing new tools and techniques for calculating precise rates for Standard Model and supersymmetric processes that match the expected experimental precision.
  7. to continue and extend contacts with physicists in North America, Asia and throughout the world. Wherever the collider is built the collaborations doing the experiments are likely to be composed of groups from all over the world - as they were at LEP and are at HERA, the Tevatron and the LHC.

The first workshop of the extended Study will be in Cracow, Poland, 15-18 September 2001. Details of registration, the programme and the working groups will be linked to this webpage.

Some of the working groups on physics and detector topics are already holding their own specialised meetings. There will be a Worldwide workshop in Korea in Summer 2002, the 5th of the LCWS series (following Saariselkä, Finland 1991; Waikoloa, Hawaii 1993; Morioka, Japan 1995; Sitges, Spain 1999; Fermilab, USA 2000). There is an open invitation for interested physicists from anywhere in the world to participate in all of these activities. The ECFA/DESY Study is likely to have a strong overlap of membership with the studies at CERN for the higher energy CLIC collider . The two studies will also share tools and ideas.

The organising committee for the extended ECFA/DESY Study is
Mikhail Danilov (ITEP, Moscow), Enrique Fernandez (Barcelona), Rolf Heuer (Hamburg), Leif Jönsson (Lund), Paolo Laurelli (Frascati), Martin Leenen (DESY), David Miller (UCL, London, chair of the Study), Walter Majerotto (Vienna), François Richard (Orsay), Albert de Roeck (CERN), Ron Settles (MPI, Munich), Janusz Zakrzewski (Warsaw), Peter Zerwas (DESY).
