Status of MedAustron Project goals, design, parameters Status und schedule Michael Benedikt CERN, BE-Department Symposium Verein AUSTRON Vienna, 15. March 2011
Goals of the MedAustron project Construction of an ion-therapy and research centre Proton and Carbon ion therapy, clinical research (incl. patient) Non clinical research (NCR) Beam operation 24/7, >300 days/y Beam time sharing clinical operation and NCR, about equal beam time Synchrotron based accelerator complex Operation phase 1: protons and C-ions Design allows for operation with other light ions (He, O,..) with q/m > 1/3 for later operation phases. 2
MedAustron Site City of Wiener Neustadt, 40 km south of Vienna Terrain 32.000 m 2 Vicinity of Fachhochschule and new hospital project WN M. Benedikt Vienna, 15.03.2011 3
Medical requirements Treatment capacity~ 1200 patients/year Centre designed for 24.000 single fractions/year corresponds to about 100 patients/day Operation concept phase 1 Medical operation 5 working days/week 2 shifts, 06:00 22:00 incl. QA Optimization of patient flow 3 medical treatment rooms 3 rooms for patient set-up per treatment room Optimum usage of accelerator complex 4
Non clinical research Medical radiation physics and radiation biology Research fields close to clinical operation (translational research) MedAustron will be state-of-the-art infrastructure for these areas Experimental physics (detector tests, nuclear physics) Increase of proton energy to (250 800 MeV) One irradiation room exclusively for NCR in addition to the three medical treatment rooms Establishing links to university and international partners essential for success and quality of research 5
Beam parameters Beam energy Protons: 60-250 MeV (medical), pulse-to-pulse modulation (ppm) Protons: up to 800 MeV for experimental physics in research room C-ions ( 12 C 6+ ): 120-400 MeV/n, ppm Beam delivery active scanning Horizontal vertical fast scanning system with magnets Energy variation directly with the synchrotron (ppm) Intensities in irradiation rooms (ppm) Dose build-up: ~ 1 minute to deliver 2 Gray in 1 liter Protons: 1*10 10 /puls C-ions: 4*10 8 /puls Repetition rate < 0.5 Hz Beam size at iso-centre 4 to 10 mm FWHM, (ppm) 6
Medical irradiation rooms Irradiation rooms IR2: horizontal- and vertical beam, identical iso-centre, p, C-ions IR3: horizontal beam, p, C-ions IR4: Gantry (-30/+180), only protons, based on PSI gantry II collaboration with PSI NCR irradiation room IR1: horizontal beam, p (up to 800 MeV), C-ions Variable iso-centre, allows 5m shift to install experiments simultaneously 7

Strategy for construction of MedAustron Accelerator complex based on existing designs, adapted to specific requirements and partially re-designed: Injector: IAP Frankfurt / SIEMENS solution (new RFQ / ITM design) Synchrotron, transfer lines: CERN/PIMMS design, CNAO techn. design Proton gantry: PSI gantry 2 design Collaborations with international partners: CNAO: synchroton and transfer line technical designs CERN: main partner for accelerator design, production, construction PSI: design/production of p-gantry, QA, interface accel.- medicine Build-up know how with an EBG core-team. In the areas accelerator technology, medicine and medical physics EBG personnel works at/with international partners during design and construction phases Contracts with medical universities and hospitals for training of physicians and medical physicists 12
Collaborations with CERN and PSI CERN is the Austrian accelerator laboratory No know-how and institution in this field in Austria MedAustron collaboration contracts with CERN: Integration of EBG MedAustron team in CERN groups, presently 33 persons working at CERN Design, procurement/production and construction of accelerator components with support of CERN Support also during installation and commissioning in WN. Excellent example for large-scale technology transfer Know-how transfer in all fields of accelerator physics Operation of the centre by the EBG MedAustron team Collaboration with PSI Integration of EBG team at PSI, set-up similar to CERN. Focus on gantry, patient alignment systems and beam delivery. 13
Status environmental impact study and CE Environmental impact assessment (accelerator > 50 MeV) All relevant legal areas (RP, statics, EL, hospital, etc.) taken into consideration. Documents submitted to authority (local government) November 2009 Permission for construction and test operation obtained in December 2010 Heavy procedure at early stage of the project, but guarantees conformity 14
Status Civil Engineering Civil engineering: Ground breaking mid February 2011 Start of construction accelerator part April 2011 (contract placed) Start of construction of clinical part May 2011. Sandwich construction of shielding walls Use of excavation material (saving of 30.000 m 3 concrete) 15
Status accelerator Accelerator complex conceptual and optics design finished Finalize technical designs Component procurement 3-D integration studies accelerator infrastructure - building Preparation of injector test stand at CERN for October 2011 16

Overall project timeline Summer 2008 Start of planning December 2010 EIA accepted, all permission for construction February 2011 Ground breaking, site preparation, CE start September 2012 Start accelerator installation Spring 2013 Start commissioning accelerator, sequential 2015 Start of medical operation 18 18
Summary MedAustron will be a state of the art ion therapie- und research centre in Austria. Project is based on international collaborations with experienced partners for the conception and construction. Collaboration with CERN is an excellent example for technology transfer. The MedAustron project advances according to schedule. Construction phase started with accelerator components and civil engineering. Goal is start of medical operation in 2015 19
