The Heidelberg Ion Therapy
Facility (HIT)H. Eickhoff
GSI, Darmstadt, Germany
2Dr. Hartmut Eickhoff, GSI
HIT Layout: RequirementsHIT Layout: Requirements
Low LET (proton, helium) and high LET (carbon and oxygen) treatment
Ion penetration depth of 20 – 300 mm
=> Ion energy range of 50 – 430 MeV/u Rasterscan method
=> FWHM of beam: 4 – 10 mm in both planes
=> Beam intensity: 1·106 – 4·1010 ions/spill
=> Extraction time: 1 – 10 s Treatment of 1000 patients per year in hospital
environment with about 15 fractions each
=> total of 15000 irradiations per year
=> three treatment areas One isocentric gantry
