    Abstract: Methods and apparatus for in-situ incline cleaning an element disposed in a EUV generating chamber are disclosed. A capillary-based hydrogen radical generator is employed to form hydrogen radicals from hydrogen gas. The capillary-based hydrogen radical generator is resistively heated during operation and is oriented such that hydrogen radicals catalytically generated from the hydrogen gas are directed to a surface of the element to clean the surface.
