  1. Report from DESY, Hamburg, Germany

  2. DESY‘s 3 Columns • Accelerator R&D Worksince 1992: superconducting linear accelerator for the TESLA LC and the X-FEL • Particle Physics1000 HEP users at HERA II3 detectors H1, ZE_US, HERMES (HERA-B finished data acquisition in Febr. this year • Synchrotron Radiation Research2000 SR users in the HASYLABHAmburg SYnchrotron radiation LAB

  3. October 2002 X-FEL Supplement TESLA and X-FEL March 2001 5-volume TESLA TDR (LC + X-FEL)

  4. The Decision • 5 February 2003Decision of the German Federal Research Ministry on Large-Scale Facilities 1) YES to the TESLA XFEL „A new free electron laser is to be built at the DESY research centre in Hamburg. In view of the locational advantage, Germany is prepared to cover half of the investment costs amounting to 673 million. Talks on European cooperation will soon start so that it will be possible to take a decision on construction within about two years. The construction period will be appr. six years.“

  5. The Decision 2) NOT YET to the TESLA LC „No German site is at present proposed for the TESLA linear accelerator. The reason is that the accelerator project will be an international collaboration. International developments must therefore be taken into account. An independent initiative by Germany concerning the site of the accelerator is neither appropriate nor necessary. DESY will, however, be able to continue its international research workso that German participation in a future global project will be possible.“ (PLUS 120 Mio Eur for PETRA III as a national project )

  6. The Decision 14 June 2003, Public Science Forum in Hamburg Research Minister Edelgard Bulmahn: “TESLA is not buried – and as well as scientists may have dreams ministers may have dreams. But from the today’s point of view, I never can’t guarantee that TESLA could be realized in 10 years or that there will be a decision on TESLA in 5-6 years.” “With the X-FEL and the PETRA III project DESY’s future is assured for a long time. Both projects are an enormous challenge and DESY enjoys the German government’s confidence of the successful realization of both projects.”

  7. The Consequence Since June 2003 DESY is on the way to change from a Particle Physics Lab with a strong Synchrotron Radiation Research Department into a Light Source Lab with Particle Physics Groups and activities

  8. DESY Status HERA II until 2006/07 With 3 detectors No HERA III possible X

  9. DESY Status Light sources for HASYLAB 43 measurement stations DORIS PETRA (test beam, parasitic)

  10. DESY Future VUV-FEL • from 2004 in operation as a user facility • based on the TESLA Test Facility • experience with sc TESLA acceleration modules

  11. DESY Future PETRA III • from 2007 rebuilding the HERA injector PETRA II • based on the TESLA Test Facility • experience with sc TESLA acceleration modules

  12. European X-FEL Lab Next 2 years: • Build-up an European X-FEL Collaboration • Preparation of the X-FEL construction approval

  13. DESY‘s HEP future • Data analysis of HERA II … 2010 ? • No experiments after 2007 (no HERA III program) • e+e- physics and detector R&D for the next LC • R&D for TESLA: sc cavities, high gradient (800 GeV) • GAN and Grid • Participate in the in the LC working groups of ECFA and ICFA

  14. DESY‘s Outreach future • DESY as a light source lab • X-FEL promotion • Communication of HERA discoveries • Outreach for pp:InterActions CollaborationEPOGELCSG-OSC
