Abstract:
Disclosed is gas delivery system which is suitable for a high harmonic generation (HHG) radiation source which may be used to generate measurement radiation for an inspection apparatus. In such a radiation source, a gas delivery element delivers gas in a first direction. The gas delivery element has an optical input and an optical input, defining an optical path running in a second direction. The first direction is arranged relative to the second direction at an angle that is not perpendicular or parallel. Also disclosed is a gas delivery element having a gas jet shaping device, or a pair of gas delivery elements, one of which delivers a second gas, such that the gas jet shaping device or second gas is operable to modify a flow profile of the gas such that the number density of the gas falls sharply.

Claim (Index 54):
The illumination source of any of  claims 45  to  53 , wherein said optical output comprises an aperture arranged to allow passage the pump radiation and to block the high harmonic radiation, the pump radiation having properties such that it is subject to greater deflection by refraction within the ionization radiation than the high harmonic radiation.
