Goals of the Study
-
To identify the important physics which can be studied in e+e-,
e-gamma, gamma-gamma or e-e- at a Linear Colliders with center of mass
energy in the range from ~200 to ~1000 GeV.
-
To perform feasibility studies on a representative set of channels,
assuming a luminosity of up to
5.1034cm-2s-1
and a realistic detector.
-
To refine the detector parameters to match the demands of the physics
programme and the constraints set by the collider.
-
To identify and foster R&D programmes which will ensure that the
required detector performance can be delivered.
-
To prepare costed designs for a suitable detector (or for two
detectors, if two collision points are found to be required, e.g. for e+e-
and gamma-gamma physics).

Milestones
-
April 1999.
International Workshop on Linear Colliders (LCWS99)
at Sitges,
near Barcelona, Spain, 28 Apr - 5 May 1999.
This was the fourth LCWS,
following Saariselka, Finland,
1991; Waikoloa, Hawaii, 1993, Morioka, Japan, 1995. Results from
the ECFA/DESY physics studies have been compared with work from the USA,
Japan, and elsewhere.
-
Mid 1999.
A web-based refereed library of reports on all aspects of
the study, including work presented at the workshops
was established:
LC Notes and
Proceedings of the Study"
A collection of
these will be printed and issued as DESY 123F to provide detailed
supporting documentation for the technical design report (TDR).
-
Spring to Autumn 2000.
Preparation and review of the draft of the costed technical proposal
(TDR) for a detector and its scientific programme by the ECFA/DESY Study.
The final draft is expected end of November 2000,
edited TDR and LC notes of backup papers expected to be available in
January 2001.
-
March 2001.
Presentation of a costed technical proposal for the TESLA
Linear Collider (TDR), its detectors and the associated programme of science,
including the results from the ECFA/DESY Study (with applications of a
superconducting linear collider as an ultra bright X-ray source and a
possible nuclear physics programme).
Contact Persons
The "Contact Persons" were nominated at the Oxford workshop to
coordinate design issues of the detector.
They are responsible for the progress on
their specific part of the detector.
Please feel free to contact them if you have questions and
let them know the progress of your work.

First announcement
ECFA - the European Committee for Future Accelerators - is organizing
a second joint study with DESY on Physics and Detectors for a
Linear Electron-Positron
Collider. The first study, in 1996/97, prepared an outline Conceptual Design
Report for a Linear Collider experiment and reported upon its considerable
physics potential; especially for Higgs boson physics, for searching for
Supersymmetric particles and for high precision measurements of the properties
of the top quark and of the electroweak gauge bosons. The results were
incorporated in a two-volume report
(ECFA 1997-182; DESY 1997-048)
which includes two alternative designs for
the linear collider; the superconducting TESLA machine
and a normally conducting
S-Band design. (The plans include facilities for other branches of science
which would utilize the linac technology, including nuclear physics and
the development and use of free electron lasers producing high quality
synchrotron radiation down to the X-ray region).
The new study has two main goals:
-
to complete the physics studies begun in 1996, using better models of the
detector.
-
to investigate the potential - and the problems - of operating the Linear
Collider and the detector at 10x the previously assumed luminosity; i.e.
at 5.1034cm-2s-1, at 500 GeV C. of M.,
and at correspondingly higher luminosities at higher energy.
Results of the physics studies will be submitted to the International Linear
Collider Workshop at Sitges, near Barcelona in the Spring of 1999 (the
next in the "LCWS" series - following Saariselka, Finland, 1991; Waikoloa,
Hawaii, 1993; Morioka, Japan, 1995), when there will be an opportunity
to compare with the plans from the USA and Japan. The eventual aim of the
study is to produce in the year 2000 a costed Technical Design Report for
the Collider and its detector with a complete physics case.
The study begins in Spring 1998. There
will be three or four workshops during 1998 at a number of European venues.
Topics to be covered include machine-detector interface, backgrounds,
triggering, physics goals, generators, detector simulation, detector performance
in specific physics analyses and detector R&D.
All of those interested in joining in should look at the
organizers website
and come to the
workshops.
