WebThe H- ions are extracted from the ion source in 200 μs long pulses to form a beam which is then passed through a 90° magnet to remove any electrons. The H- ions acquire an energy of 35 keV across a DC acceleration gap, are focused and monitored in the Low Energy Beam Transport and then passed into the Radio Frequency Quadrupole (RFQ) accelerator. Web4 feb. 2024 · Radiation therapy is one of the most widely used therapies for malignancies. The therapeutic use of heavy ions, such as carbon, has gained significant interest due to advantageous physical and radiobiologic properties compared to photon based therapy.
