Abstract:
1. A source of radiation in the extreme ultra-violet (EUV), the source comprising means ( 7 , 15 ) for injecting a stream of radiation-generator material into the inlet of an irradiation zone ( 3 ), means ( 8 , 16 ) for picking up the stream of radiation-generator material leaving the irradiation zone ( 3 ), means for generating and focusing power laser radiation ( 5 , 6 ) on the radiation-generator material in the irradiation zone ( 3 ), means ( 13 ) for collecting and conditioning the EUV radiation emitted by the radiation-generator material in the irradiation zone ( 3 ), and first vacuum generator means ( 11 ) connected to an irradiation chamber ( 1 ) in which the irradiation zone ( 3 ) is situated for maintaining a first pressure (P 1 ), the source being characterized in that: the means ( the transmission chamber ( the stream of radiation-generator material in the irradiation zone (
