  • HERAAssure continued operation of HERAAssure high integrated luminosity for the three experiments H1, ZEUS, HERMES until the end of running of HERA, December 2006/June 2007Lifetime: 1992 - 2007

    Albrecht Wagner

  • HERAQuestions:How big are electron and quarkWhat is the proton made ofWhich properties do the fundamental forces haveWhat is the origin of spinAre there new phenomena

    First collisions in 1992Luminosity upgrade in 2000HERA: Microscope - unique world-wide - with a resolution of 1/1000 of proton radius (10-18 m)

    Albrecht Wagner

  • HERA RunningThe 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 spikes need to be removed

    very low 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

  • XFEL a revolutionary photon sourceThe excellent beam properties in the superconducting TESLA-LINAC allow to use the SASE (Self Amplifying Spontaneous Emission) principleBrillance: gain ~ 109 compared to existing facilitiesPhoton beam: X-rays at 0.1 nm Full coherence (Laser) Pulse length < 100 fs (time scale of chemical reactions) Energy tuneable

  • The Story of SC CavitiesSC 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

  • 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 linacJINR is member since 1995, many important contributions

  • The Scientific Case for a LCA world-wide consensus has formed for a baseline LC project in which positrons collide with electrons at 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

  • e+e- Colliders:The ChallengesThe challenges:Luminosity:high charge density (1010), > 10,000 bunches/svery 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 LCs world-wideFor E > 200 GeV need to build linear colliders

    Proof of principle:SLC

  • The Elements of DESYThe strength of DESY lies in its structure: Leading role in accelerator development (SC RF acceleration)Clearly defined projects for the next 15-20 years

  • DESY SummaryDESY 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 partnershipThe 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
