Abstract: An ion therapy system for irradiating a patient with laser-accelerated ions may include a laser radiation source to emit laser radiation and a housing coupled to the laser radiation source. The system may have a laser target having a surface from which an ion beam can be generated. The housing may have a window portion to let an incident ion beam pass and to seal the housing. The system may have a vacuum system to generate lower pressure in the inner space of the housing. A focusing system may focus the laser radiation on the laser target. A control device may control the focusing system and adjust a propagation direction of the ion beam such that the ion beam impinges on an external target. The laser radiation source may generate laser pulses with a duration between 10−18 seconds and 10−12 seconds and an energy of at least 100 mJ.
