Title:
ION GENERATION DEVICE, PARTICLE BEAM ACCELERATION DEVICE AND PARTICLE BEAM THERAPY SYSTEM
Document Type and Number:
Japanese Patent JP2023009327
Kind Code:
A
Abstract:
To increase the pulse width of an ion beam generated by an ion generation device.SOLUTION: An ion generation device 20 comprises laser devices 2a and 2b. The ion generation device 20 also comprises laser optical paths 3a and 3b provided corresponding to the laser devices 2a and 2b, a wave plate 5 and a beam splitter 4. The laser optical paths 3a and 3b have optical path lengths different from each other. The laser optical paths 3a and 3b guide laser beams generated by the laser devices 2a and 2b to the beam splitter 4, respectively. The beam splitter 4 integrates the light guided to the laser optical paths 3a and 3b and irradiates a target 14 with the integrated light. The target 14 generates ions according to the light irradiated from the beam splitter 4.SELECTED DRAWING: Figure 1
