1 Dr. Hartmut Eickhoff, GSI 1 Heavy Ion Cancer Therapy The Heidelberg Ion Therapy Facility (HIT) H. Eickhoff GSI, Darmstadt, Germany

2 Dr. Hartmut Eickhoff, GSI 2 HIT Layout: Requirements n Low LET (proton, helium) and high LET (carbon and oxygen) treatment n Ion penetration depth of 20 – 300 mm => Ion energy range of 50 – 430 MeV/u n Rasterscan method => FWHM of beam: 4 – 10 mm in both planes => Beam intensity: 1·10 6 – 4·10 10 ions/spill => Extraction time: 1 – 10 s n Treatment of 1000 patients per year in hospital environment with about 15 fractions each => total of 15000 irradiations per year => three treatment areas n One isocentric gantry

3 Dr. Hartmut Eickhoff, GSI 3 Treatment Technique: Rasterscan n Intensity-controlled Rasterscan-method

4 Dr. Hartmut Eickhoff, GSI 4 Schedule n 1997First patient treatment at GSI n 1998HICAT Conceptual design report n 2000Technical design report n May 2001Approval by Scientific Council of Germany n April 2003Final Approval by Supervisory board of Heidelberg University Hospital n Autumn 2003Start of construction n End of 2005Start assembly of accelerator systems n Year 2006/7Commissioning n End 2007First patient treatment in Heidelberg n Mid of 2008Hand-over to clinics operation

5 Dr. Hartmut Eickhoff, GSI 5 HIT Layout: System Plan n Accelerator sections n Two ECR sources n Injector linac n Synchrotron n Extraction via RF knock out n Two horizontal areas n One Gantry n One quality assurance place n Compact design (area restrictions)

6 Dr. Hartmut Eickhoff, GSI 6 GSI- and HIT-facility (comparison of size) The GSI-accelerator facility The HIT facility comparison of the size of the facilities

7 Dr. Hartmut Eickhoff, GSI 7 HIT Layout: Injector System Ion source IH - model n Features n Based on GSI experience n compact n reliable n Low operation costs n Fast switching of ions

8 Dr. Hartmut Eickhoff, GSI 8 HIT Layout: Synchrotron n Features n Compact (diameter 20m) n Conventional, approved technique n Multiturn injection n Multiple beam extraction (transverse KO-method) n Range of factor 16 for magnetic rigidity (factor 6 for extraction)

9 Dr. Hartmut Eickhoff, GSI 9 HIT Layout: Gantry n Features n First heavy ion gantry n Close to 600 to. weight n 13 m diameter n Maximum deformation of 0.5 mm n Integration of rasterscan
