    Abstract: A metrology system includes a light beam metrology apparatus configured to sense one or more aspects of an amplified light beam and to make adjustments to the amplified light beam based on the sensed one or more aspects; a target metrology apparatus configured to measure one or more properties of a modified target after a target has interacted with the amplified light beam, and to determine a moment when the modified target achieves a reference calibration state; and a control apparatus configured to: receive the reference calibration state and the moment at which the reference calibration state is achieved from the target metrology apparatus; determine a light beam calibration state of the amplified light beam based on the received reference calibration state and the moment at which the reference calibration state is achieved; and provide the light beam calibration state to the light beam metrology apparatus.

    Abstract: A radiation source comprises: an emitter for emitting a fuel target towards a plasma formation region; a laser system for hitting the target with a laser beam to generating a plasma; a collector for collecting radiation emitted by the plasma; an imaging system configured to capture an image of the target; one or more markers at the collector and within a field of view of the imaging system; and a controller. The controller receives data representative of the image; and controls operation of the radiation source in dependence on the data.
