Therapy Accelerator
A dedicated clinical cancer therapy facility was designed at GSI and was build at the Radiologische Universitätsklinik in Heidelberg, Germany. The facility is designed to treat more than 1000 patients per year using the intensity controlled rasterscan method, which was developed at GSI and was successfully applied at GSI with carbon ion beams to more than 400 patients from December 1997 until 2009. Patient treatment at HIT started in November 2009.
A Selection of beam parameters required at the treatment places (upper part) and major linac parameters (lower part) are listed in the following Tables.
Major treatment parameters:
Ion species | p,3He2+,12C6+, 16O8+ |
Ion energies | 48 - 430 MeV/u |
Max. beam intensities | 1·10912C6+ions/spill 4·1010 protons/spill |
Beam contaminations | < 1% |
Major linac parameters:
Measured ion beam | H3+: 700 µA, 3He+: 840 µA |
Currents behind analyzing slits | 12C4+: 200 µA, 16O6+: 170 µA |
Final beam energy | 7 MeV/u |
Operating frequency | 216.816 MHz |
Beam pulse length and repitition rate | ≤ 300 µs @ PRF ≤ 5 Hz |
