Cooperation with slac on fel

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.

Albrecht Wagner, ECFA/DESY, Prague, Nov02


Status and next steps

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

Organisation and management

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


The project parties

The Project Parties

The funding sources which create and sustain theTESLA Projectare 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


The tesla board

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


The joint tesla office

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


The executive agencies

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 Officeand 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


The regional project offices

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


The integrated product teams

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

Albrecht Wagner, ECFA/DESY, Prague, Nov02

OECD Consultative Group

... Discussion on organisational issues etc

It was decided to continue these OECD discussions…..

Albrecht Wagner, ECFA/DESY, Prague, Nov02


Continuation of cg

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

Albrecht Wagner, ECFA/DESY, Prague, Nov02


New ecfa study on physics and detectors for a lc

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 studies.

  • The present ECFA/DESY Study involves a widely distributed group of experimenters and theorists doing feasibility studies, fundamental calculations and R&D.

  • 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.

Conclusion

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
