Abstract: A debris mitigation system for use in a radiation source. The debris mitigation system comprises a contamination trap. The contamination trap comprises a debris receiving surface arranged to receive liquid metal fuel debris emitted from a plasma formation region of the radiation source. The debris receiving surface is constructed from a material that reacts with the liquid metal fuel debris to form an intermetallic layer on the debris receiving surface.
