AUSTRON / Med - AUSTRON

RECFA – Meeting

Innsbruck

March 26, 2004

M. Regler

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 Spallation Source, 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

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

Continuation 1995

• Continuation with a very small team at CERN and in Austria (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

AUSTRON

• 1996 Hearing by the European Science Foundation• 1997 recommendation to the Austrian Government to

build 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”)

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 !!!
