  2. DESY - Research • Study of the structure of matter from macroscopic to atomic scale at DORIS, PETRA and XFEL • Structure of elementary particles, forces + origin of mass at (DORIS, PETRA), HERA, and a future LC • Theory in particle physics + cosmology(including lattice gauge theory + development of specialised computers) • Origin of cosmic high energy neutrinos(Amanda, IceCube at the South Pole) • Detector R&D • Accelerator R&D Albrecht Wagner

  3. DESY’s Accelerators - today DESY-DORIS-PETRA-HERA: In total 16 km of accelerators TTF-Linac: Photo-Injector at Zeuthen: Albrecht Wagner

  4. HERA Assure continued operation of HERA Assure high integrated luminosity for the three experiments H1, ZEUS, HERMES until the end of running of HERA, December 2006/June 2007 Lifetime: 1992 - 2007 Albrecht Wagner

  5. HERA HERA: Microscope - unique world-wide - with a resolution of1/1000 of proton radius (10-18 m) • Questions: • How big are electron and quark • What is the proton made of • Which properties do the fundamental forces have • What is the origin of spin • Are there new phenomena • First collisions in 1992 • Luminosity upgrade in 2000 Albrecht Wagner

  6. HERA Running The HERA performance is further improving, the currents are increasing (Ip: >90 mA (90); Ie: >40 mA (50)) The background conditions even at high currents are good, but coasting beam and spikesneed to be removed Albrecht Wagner

  12. PETRA III Layout Albrecht Wagner

  13. DESY Strategy 2005 – 2009: PETRA III • Strategy: • start of reconstruction:2007 • first users:2009 • verylow emittance mainly for hard X-rays • open for future upgrades • concept of outstations (e.g. EMBL, GKSS) • 13 independent undulator beamlines, of which • 7 undulator beamlines built and operated by DESY • 1.5 beamlines financed by MPG (construction and operation) • 4-5 undulator beamlines expected to be operated in collaboration • with external institutions (GKSS, EMBL, …) • provide users with first class sample environment and a service comparable to ESRF Parameters: - rebuilt of 1/8 of PETRA - refurbishment of 7/8 of PETRA - energy: 6 GeV - top up operation mode Albrecht Wagner

  14. XFEL a revolutionary photonsource The excellent beam properties in the superconducting TESLA-LINAC allow to use the SASE(Self Amplifying Spontaneous Emission) principle Brillance:gain ~ 109 compared to existing facilities Photon beam: • X-rays at 0.1 nm • Full coherence (Laser) • Pulselength < 100 fs (time scale of chemical reactions) • Energy tuneable Albrecht Wagner

  15. The Story of SC Cavities SC RF structures for accelerators were developed in many countries To meet the challenge of high gradients needed for high energy Linear Colliders the TESLA collaboration has attracted ~ all the world expertise in SC, thus leading to major progress Albrecht Wagner

  16. The TESLA Collaboration • The TESLA Collaboration: • at present 55 Institutes in 12 countries • These institutes have contributed through hardware, manpower, and ideas to the facility and share the know-how concerning the construction and operation of the Sc linac • JINR is member since 1995, many important contributions Albrecht Wagner

  17. Science with the X-FEL • Main fields of research with the X-FEL: • atomic, molecular and cluster phenomena, plasma physics • non-linear processes and quantum optics • condensed matter physics and materials science • ultra-fast chemistry and life-sciences Movies of chemical reactions Plasma physics Albrecht Wagner

  23. European XFEL Laboratory time schedule 1200 m 2000 m start in 2005 ●●●●●●●●●●●●●●● complete in 2011 Albrecht Wagner

  24. Linear Collider Play leading role in this new develpoment of particle physics Continue R&D in international context, to prepare the German participation in a world-wide project The Technical Design Report incl. cost was published in March 2001 Albrecht Wagner

  25. The Scientific Case for a LC A world-wide consensus has formed for a baseline LC project in which positronscollide with electronsat energies up to 500 GeV, with luminosity above 1034 cm-2s-1. The energy should be upgradable to about 1 TeV. Above this firm baseline, several options are envisioned whose priority will depend upon the nature of the discoveries made at the LHC and in the initial LC operation. The consensus document has been signed by > 2600 scientists from all around the world. http://www-flc.desy.de/lcsurvey/ Substantial overlap in running with LHC recommended Albrecht Wagner

  26. e+e- Colliders:The Challenges For E > 200 GeV need to build linear colliders Proof of principle: SLC The challenges: Luminosity: high charge density (1010), > 10,000 bunches/s very small vertical emittance (damping rings, linac) tiny beam size (5*500 nm) (final focus) Energy: high accelerating gradient (> 25 MV/m, 500 - 1000 GeV) To meet these challenges: A lot of R&D on LC’s world-wide Albrecht Wagner

  27. High Gradients in EP nine-cell Cavities High gradients is a high priority item at DESY and in TESLA collab. • Test of 1/8th of a TESLA cryomodule at 5 Hz, 500 ms fill, 800ms flat-top • ->35 MV/m • with no interruption related to cavity-coupler-klystron for more than 1000 hours • No field emission AC70: gradient of 39.4 MV/m at 2K using EP at DESY not treated at 1400 C Albrecht Wagner

  28. Next Milestones towards a Global Linear Collider • Selection of Collider Technology (warm or cold) and setting up of an international project team with branches in America, Asia and Europe • Continuation of discussion between funding agencies • Further studies of organisation structures • Start of work of project teams (‚Global Design Initiative‘) • Completion of the project layout (CDR) including costing • Submission of TDR to governments to go ahead with LC • 2009 Start major spending • 2015 Start of commissioning Albrecht Wagner

  29. Exp. & Theor. Particle Physics Accelerators & Development Photon Research SR & FELs Upgrade Project: PETRA SR Current Projects: HERA DORIS VUV-FEL + Photoinjector Amanda/Icecube European Facility: XFEL Planned Global Project: LC The Elements of DESY The strength of DESY lies in its structure: Leading role in accelerator development (SC RF acceleration) Clearly defined projects for the next 15-20 years Albrecht Wagner

  30. DESY Summary • DESY has a long history in particle physics, research with synchrotron radiation and accelerator development. These field are of strong mutual benefit for each other • Very successful development of the superconducting accelerating technology in international partnership • The activities of the TESLA collaboration have influenced significantly many other accelerator projects • The European X-FEL laboratory will provide a new generation of photon source based on the TESLA technology • Strong world enthusiasm for a LC, aiming at political decision in 2007 Albrecht Wagner
