WR-Recommendation concerning TESLA
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 TESLA 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 trendsetting 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 2003

ELCSG Subgroup on
Organisational Matters
The charge is:
• From a European Perspective,
work out possible models for the
design, construction and
operation of a linear collider* as
a truly international project.
• Develop a 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
Albrecht Wagner, ECFA/DESY, Prague, Nov02
23
The Project Parties
The funding sources which create and sustain the TESLA
Project are called the Parties. The Parties have two initial
responsibilities:
• To establish jointly, and by agreement, an oversight body
for the Project, the TESLA Board. The TESLA Board has
the responsibility to establish and supervise the Project.
• To each appoint Executive Agencies, or Executives, to
provide the overall management of those Project tasks and
responsibilities that are agreed to belong to each of the
Parties. If desired, several parties can appoint a joint
Executive.
Albrecht Wagner, ECFA/DESY, Prague, Nov02
24
The TESLA Board
•
The TESLA Board is the oversight body for the Project, it
has the responsibility to establish and supervise the Project.
•
The TESLA Board
– organises the Joint TESLA Office (JTO) that directs
and manages the overall Project.
– It appoints the senior management, specifically the
Directors.
– It defines the responsibilities and authorities of each of
the key personnel.
– It appoints the Science Advisory Committee and the
Management Advisory Committee.
Albrecht Wagner, ECFA/DESY, Prague, Nov02
25
The Joint TESLA Office
The Joint TESLA Office (JTO) carries out its management function
by specifying the scope, schedule, and tasks of the Project
and
by managing the efforts of the Executives to provide the
necessary deliverables.
The Joint TESLA Office is responsible for the implementation of
the Project.
It is led by a small board of Directors and includes the top-level
organisation.
The Directors have the responsibilities and authorities as defined
by a special agreement.
Albrecht Wagner, ECFA/DESY, Prague, Nov02
26
The Executive Agencies
•The Executive Agencies, or Executives,
– provide the overall management of those Project tasks and
responsibilities that are agreed to belong to their funding
Parties.
- staff and fund the TESLA Project.
-are legal entities and can enter into contracts, employ staff,
etc., on behalf of the Project.
• It is proposed to have at least three Executives, representing the
Americas, Asia, and Europe, combined with a range of regional
agreements.
• In order to carry out their project functions each of the
Executives will create a Regional Project Office and secure for
that office the staff and resources necessary for the performance
of the tasks assigned to that Executive.
Albrecht Wagner, ECFA/DESY, Prague, Nov02
27
The Regional Project Offices
• The work packages will be carried out by existing institutions in
the different regions, under the responsibility of the Regional
Project Offices.
• The Regional Project Offices will be responsible for ensuring that
the resources are made available to carry out the work packages to
performance and schedule.
• Each work package will be covered by a formal agreement between
the institutions concerned.
Albrecht Wagner, ECFA/DESY, Prague, Nov02
28
The Integrated Product Teams
• The project management structure is based on the concept of
Integrated Product Teams (IPTs).
• The Integrated Product Teams manage the individual tasks, as
defined in the first level of the Work Breakdown Structure.
• The implementation of IPTs as task managers reflects the fact
that the responsibility for most subsystems are shared between
different institutions and even regions. This is to exploit best the
know-how available around the globe and to ensure that the knowhow is shared between the several Executives. For this reason the
leadership for those level-1 tasks is also shared.
• Each IPT consists of all those individuals who are assigned by one
or several of the Executives with significant responsibility for work
elements within a given level-1 WBS task.

GAN
Remote operation will very
likely be of key importance
for the future operation
of large facilities.
Key issues:
• social aspects
Tests in this area are
ongoing or planned (TTF,
A0, LINX, PI3…)
ICFA is considering to sponsor future GAN workshops

OECD Consultative Group
... Discussion on organisational issues etc
It was decided to continue these OECD discussions…..
Albrecht Wagner, ECFA/DESY, Prague, Nov02
33
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 03

New ECFA Study on Physics and Detectors for a LC
1.
The organising committee of the Extended ECFA/DESY Study
proposes that ECFA should support these activities for a further
two years, from Spring 2003.
2. 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 studies.
3. The present ECFA/DESY Study involves a widely distributed
group of experimenters and theorists doing feasibility studies,
fundamental calculations and R&D.
4. 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.
5. 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.

Conclusion
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, inspite the fierce
competetive atmosphere
Organisational aspects are being addressed
The community is organising itself internationally
The political discussions have started
