  1. AUSTRON / Med - AUSTRON RECFA – Meeting Innsbruck March 26, 2004 M. Regler

  2. Early History • April 20, 1990: First presentation of a project frame at the RECFA Meeting at the Austrian Academy of Sciences by M. Regler (Co – author W. Mitaroff): Project for an international broad-field research and high-tech centre in Austria – AUSTRON • The final specification of the project – a SpallationSource, was taken in April 1991 at a Meeting of the “Working Group on Science and Technology” of the “Central European Initiative” (CEI, former Hexagonale, former Pentagonale) in Bratislava • October 1991: Workshop at CERN (hosted by C. Rubbia, organized by M. Regler): Quite detailed conceptual design report with a realistic cost estimate

  3. Specifications • Rapid Cycling Synchrotron 1.6 GeV / 25Hz / 100 kW with 4 kJ p/pulse on target; edge cooled target • Medical facility with protons and carbon ions • Total cost: 225 MEUR (prices 1991, without med. fac.) • 1993/ 94: Feasibility Study (responsible: M. Regler, Accelerator group hosted at CERN with project leader Ph. Bryant (other members paid by Austria), project leader for target and experiments M. Schuster) • Ready December 1994: 200 kW (by increased injection energy, 70 > 130 MeV, Nr. of protons p/pulse: 3.2*1013 • Separate Medical Facility similar to the EULIMA design

  4. Continuation 1995 • Continuation with a very small team at CERN and inAustria (much weekend support by Austrian staff members at CERN): 0.5 MW with a dual frequency magnet cycle (33/100 Hz); target still edge cooled (W5Re = Tungsten with 5% Rhenium) • Foundation of the AUSTRON Society (Regler/Skalicky (rector of the Univ. of Technology Vienna)) • Feasibility Study of a Medical stand - alone Facility financed by the City of Wiener Neustadt and the province of Lower Austria until 1999 • Joint effort Med-AUSTRON – TERA – CERN resulting in the encouraging PIMMS study (Austria: 3 PhD students) • Special Austrian contribution: Riesenradgantry

  5. AUSTRON • 1996 Hearing by the European Science Foundation • 1997 recommendation to the Austrian Government tobuild AUSTRON after additional studies, mainly in the field of advanced and efficient instruments • 1998: As a parallel result of this additional studies: Storage Ring to deliver 500kW at 10 Hz > 2*1014 protons p/pulse (pulse length ~ 1 000 ns) • Peak neutron flux 4*1016/cm2s • 1999 – 2000: International contacts at the highest level, but • These activities were not really supported by the Austrian neutron scattering community! (“Dormant project”)

  6. Med - AUSTRON • 2001 unanimous support by the Austrian Society of Radiooncology • 5 MEUR for “fotec” in Wiener Neustadt(director E. Griesmayer) for additional studies (25% medicine and biology, project leader Dr. Auberger (Innsbruck), 75% for accelerator studies (chief consultant A. Wrulich, supported by H. Schoenauer and many others), economic evaluation and PR) • Collaboration with the EU-ENLIGHT project, with CERN, “TERA”, GSI, Lyon, now also with SIEMENS • Waiting for Federal Government !!!
