Abstract
At least one exemplary embodiment is directed to a light source which includes a plasma generator configured to generate plasma, a mirror configured to reflect light that is produced by the plasma, a plurality of plates provided between the plasma and the mirror and arranged radially around an axis passing through a light emission center, and a magnetic-field generator for generating a magnetic line of force between the plasma and the mirror so that trajectories of charged particles scattering from the plasma are curved toward the plates.
