Abstract
Generation of impurity ions is prevented or reduced in a carbon ion generating device in which a laser-driven ion acceleration system is employed. A carbon ion generating device generates a carbonized region by irradiating a film made of an organic compound with a first laser beam, and generates carbon ions by irradiating at least a part of the carbonized region with a second laser beam.
Claims14
A carbon ion generating device comprising:
- a first laser irradiation mechanism that generates a carbonized region by irradiating a part of a film made of an organic compound with a first laser beam so as to carbonize the part;
- and
- a second laser irradiation mechanism that generates carbon ions from the carbonized region by irradiating at least a part of the carbonized region with a second laser beam.
