Summary: | A radiation source contains a collector module comprising an optical collector, positioned in a vacuum chamber with an emitting plasma, further comprising a means for debris mitigation which include at least two casings arranged to output debris-free homocentric beams of the short-wavelength radiation, coming to the optical collector preferably consisting of several identical mirrors. Outside each casing there are permanent magnets that create a magnetic field inside the casings to mitigate charged fraction of debris particles and provide the debris-free homocentric beams of short-wavelength radiation. Other debris mitigating techniques are additionally used. Preferably the plasma is laser-produced plasma of a liquid metal target supplied by a rotating target assembly to a focus area of a laser beam. The technical result of the invention is the creation of high-powerful high-brightness debris-free sources of short-wavelength radiation with large, preferably more than 0.25 sr, collection solid angle. |
