A plurality of magnet devices is arranged within the ion acceleration tube; the directions of the lines of magnetic force formed respectively by the magnet devices are made to differ between the adjacent magnet devices by an angle of more than 0 degree and at most 90 degrees or less; and each of the lines of magnetic force is rotated in one direction within the ion acceleration tube.

| An EUV light source serves for generating a usable output beam of EUV illumination light for a projection exposure apparatus for projection lithography. The light source has an EUV generation device which generates an EUV raw output beam. The latter is circularly polarized. For the purposes of setting the polarization of the usable output beam and in respect of the polarization direction, a polarization setting device has a linearly polarizing effect on the raw output beam. This results in an EUV light source, which provides an improved output beam for a resolution-optimized illumination. | ||||||

| An array of spatially separated beamlets is produced by a corresponding array of charged particle emitters. Each emitter is at an electrostatic potential difference with respect to an immediately adjacent emitter in the array. The beamlets are converged laterally to form an charged particle beam. The beam is modulated longitudinally with infrared radiation to form a modulated beam. The charged particles in the modulated beam are bunched longitudinally to form a bunched beam. The bunched beam may be modulated with an undulator to generate a coherent radiation output.
