• Project goals, design, parameters• Status und schedule

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.

MedAustron Site

M. Benedikt

• City of Wiener Neustadt, 40 km south of Vienna• Terrain 32.000 m2

• Vicinity of Fachhochschule and new hospital project WN

Vienna, 15.03.2011

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

M. Benedikt Vienna, 15.03.2011

5

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

M. Benedikt Vienna, 15.03.2011

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 (12C6+): 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*1010 /puls– C-ions: ≤ 4*108 /puls– Repetition rate < 0.5 Hz

• Beam size at iso-centre– 4 to 10 mm FWHM, (ppm)

Irradiation rooms• Medical 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

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

M. Benedikt Vienna, 15.03.2011

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.

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

M. Benedikt Vienna, 15.03.2011

15

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 m3 concrete)

M. Benedikt Vienna, 15.03.2011

16

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

Status procurement – accelerator, medicine

• Accelerator:– Placed contracts (~30% of total)

• Magnet steel 700 t (all magnets)• 3 ECR ion sources and spectrometers• RFQ und IH tanks• RF amplifiers for RFQ, IH, (de)buncher,• Main dipole magnets synchrotron• Quadrupole magnets HEBT, MEBT• Framework contract control system• Power converters

• Large medical equipment and software systems: – Invitations to tender ongoing/in preparation
