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
