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 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
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

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
24
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.

25
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.

26
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.

27
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.

28
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.

29
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 know-how 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
32
OECD Consultative Group
33
OECD Consultative Group
... Discussion on organisational issues etc It
was decided to continue these OECD discussions..
34
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

35
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 RD.
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
