INTRA-OPERATORY CARBON ION RADIATION THERAPY SYSTEM

摘要

Intra-operatory ion therapy system for irradiating a patient with laser-accelerated ions, preferably carbon ions, henceforth referred to as "Ion therapy system", comprising a laser radiation source adapted to emit laser radiation, a housing, being arranged and connected to the laser radiation source, such that laser radiation emitted from the laser radiation source can be coupled into the housing, a laser target onto which the laser radiation emitted from the laser radiation source can be focussed and from which surface an ion beam can be generated, a window portion in the housing adapted to let an incident ion beam pass the window portion to the outside of the housing at minimum energy loss and adapted to seal the housing, a vacuum system for generating lower pressure in the inner space of the housing, a focussing system for focussing the laser radiation on the laser target, holding means for holding the laser target and a control device for controlling the focussing system and the holding means and for adjusting the propagation direction of the ion beam such that the ion beam impinges on an external target, wherein the laser radiation source is adapted to generate laser pulses with a duration between 10 ^-18 s and 10^-12s and an energy of at least 100mJ and a method for generating an ion beam.
