Abstract:
A system and method of removing target material debris deposits simultaneously with generating EUV light includes generating hydrogen radicals in situ in the EUV vessel, proximate to the target material debris deposits and volatilizing the target material debris deposits and purging the volatilized target material debris deposits from the EUV vessel without the need of an oxygen containing species in the EUV vessel.

Claim (Index 6):
The EUV light source of  claim 1 , wherein the first hydrogen radical source produces hydrogen radicals in a manner that prevents an oxygen containing species from entering the EUV vessel.
