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 23):
A gas delivery system according to any of  claims 19  to  22 , wherein the gas jet shaping element is located such that a wall of the gas jet shaping element is located between the pump radiation interaction region and the optical output, and no wall of the gas jet shaping element is located between the gas pump radiation interaction region and the optical input.
