The invention is directed to an arrangement for generating extreme
ultraviolet radiation from a plasma generated by an energy beam with high
conversion efficiency, particularly for application in radiation sources
for EUV lithography. It is the object of the invention to find a novel
possibility for generating EUV radiation by means of a plasma induced by
an energy beam that permits a more efficient conversion of the energy
radiation into EUV radiation in the wavelength region of 13.5 nm and
ensures a long lifetime of the optical components and the injection
device. According to the invention, this object is met by using a mixture
of particles with a carrier gas and the target feed device has a gas
liquefaction chamber, wherein the target material is supplied to the
injection unit as a mixture of solid particles in liquefied carrier gas,
and a droplet generator is provided for generating a defined droplet size
and series of droplets, wherein means which are controllable in a
frequency-dependent manner and which are triggered by the pulse frequency
of the energy beam are connected to the injection unit for the series of
droplets.
