    Abstract: A difficulty of contamination interfering with a grid plate positional measurement system is addressed. In one embodiment contamination is prevented from coming into contact with the grating or the sensor. In an embodiment, surface acoustic waves are used to detach contamination from a surface of the grating or sensor.

    Abstract: A fluid handling structure comprising a conduit is described. The conduit is configured to supply fluid to (i) a space between a projection system and a substrate and/or substrate table, and/or (ii) a top surface of a substrate and/or substrate table radially outward of the space. The fluid comprises a fluid in a first phase and a fluid in a second phase. The conduit comprises at least two openings, a first phase fluid opening configured to allow passage of the first phase fluid and a second phase fluid opening configured to allow passage of the second phase fluid. There is also disclosed a table and a lithographic apparatus comprising such a conduit, as well as a method in which the conduit is used.
