Abstract: An extraction body for a support apparatus of a lithographic apparatus. The support apparatus is configured to support an object. The extraction body is formed with an opening at a surface thereof. The opening extends within the extraction body forming a first passageway. The first passageway is configured to fluidly communicate an extraction channel in the extraction body to liquid between the surface and the object. A first pressure in the extraction channel is less than ambient pressure. At least a part of the first passageway is sized and dimensioned such that when the liquid enters the first passageway via the opening, a second pressure in the first passageway associated with surface tension of the liquid is lower than the first pressure such that at least a portion of the liquid is retained in the first passageway.

Abstract: A passive flow induced vibration reduction system for use in a temperature conditioning system that controls the temperature of at least one component within a lithographic apparatus. This FIV reduction system includes: a conduit that provides a flow path for a liquid through the system; a liquid filled cavity in fluid connection with the conduit, wherein the fluid connection is provided via one or more openings in the wall of the conduit; a membrane configured such that it separates the liquid in the liquid filled cavity from a gas at a substantially ambient pressure and the membrane is configured such that compliance of the membrane reduces at least low frequency flow induced vibrations in the liquid flowing through the conduit; and an end-stop located on the gas side of the membrane, wherein the end-stop is configured to limit an extent of deflection of the membrane.
