Claim:
1. Substrate processing apparatus, comprising: a support frame; a radiation projection system for projecting radiation onto a substrate to be processed, the radiation projection system comprising a cooling arrangement and being supported by the support frame via one or more pendulums, so that the radiation projection system and the cooling arrangement are moveable relative to the support frame and are vibrationally decoupled from the support frame, such that vibrations of the support frame above a predetermined maximum frequency are substantially decoupled from the radiation projection system and the cooling arrangement; a substrate support structure provided with a surface for supporting the substrate to be processed; and a fluid transfer system for providing fluid to and removing fluid from the cooling arrangement of the radiation projection system, wherein the fluid transfer system comprises at least one tube, a first fixation element and a second fixation element, wherein the at least one tube is fixed at least by the first and second fixation elements at a first fixed point and a second fixed point within the apparatus, wherein the said at least one tube of the fluid transfer system comprises a flexible portion extending between the first and second fixed points, the first fixed point being fixed relative to the support frame, and the second fixed point being fixed relative to the radiation projection system and to said cooling arrangement, wherein the first and second fixed points and at least a substantial part of the flexible portion are arranged in a same plane substantially parallel to the surface of the substrate support structure, so that the flexible portion extends substantially along a curve in the same plane substantially parallel to the surface of the substrate support structure so as to attenuate vibrations in the plane and between the first fixed point and the second fixed point, and wherein the stiffness of the flexible portion between the two points is adapted to substantially decouple vibrations at the second fixed point which are above the predetermined maximum frequency from the first fixed point.
