Abstract
A source hollow body serves for predefining a plasma chamber for a section of a source plasma of an EUV plasma light source. The hollow body has at least one chamber wall that delimits the plasma chamber. The chamber wall has a multilayer construction. This results in a source hollow body that improves the practical usability of an EUV plasma light source equipped with the source hollow body.
