    Abstract: A method of thermally conditioning a physical object, includes guiding a two-phase cooling medium through a cooling duct of the physical object, wherein the guiding includes: guiding the two-phase cooling medium in a liquid phase via a pre-heating duct of the physical object from a supply side of the physical object at least partly towards a discharging side of the physical object, the two-phase cooling medium being pre-heated in the pre-heating duct; guiding the two-phase cooling medium from the pre-heating duct to a phase transitioning duct of the physical object, the two-phase cooling medium at least partly transitioning from the liquid phase towards a gas phase in the phase transitioning duct; guiding the two-phase cooling medium from the phase transitioning duct to a discharging duct of the physical object; and discharging at the discharging side the two-phase cooling medium from the discharging duct.

    Abstract: A lithographic apparatus component, such as a metrology system or an optical element (e.g., a mirror) is provided with a temperature control system for controlling deformation of the component. The control system includes channels provided close to a surface of the component through which a two phase cooling medium is supplied. The metrology system measures a position of at least a moveable item with respect to a reference position and includes a metrology frame connected to the reference position. An encoder is connected to the moveable item and constructed and arranged to measure a relative position of the encoder with respect to a reference grid. The reference grid may be provided directly on a surface of the metrology frame. A lithographic projection apparatus may have the metrology system for measuring a position of the substrate table with respect to the projection system.

    Abstract: A displacement measurement system comprising at least one retro reflector and a diffraction grating. Said displacement measurement system is constructed and arranged to measure a displacement by providing a first beam of radiation to the measurement system, wherein the diffraction grating is arranged to diffract the first beam of radiation a first time to form diffracted beams. The at least one retro reflector is arranged to subsequently redirect the diffracted beams to diffract a second time on the diffraction grating. The at least one retro reflector is arranged to redirect the diffraction beams to diffract at least a third time on the diffraction grating before the diffracted beams are being recombined to form a second beam. And the displacement system is provided with a sensor configured to receive the second beam and determine the displacement from an intensity of the second beam.
