    Abstract: A fuel supply for an EUV radiation source is disclosed. The fuel supply comprises a reservoir (40) for retaining a volume of fuel (42), a nozzle (32), in fluid connection with the reservoir, and configured to direct a stream of fuel along a trajectory towards a plasma formation location, and a fuel contamination control arrangement (44) which separates contamination particles from the fuel. The contamination control arrangement comprises at least one acoustic filter. The acoustic filter may apply an acoustic standing wave to the fuel. Also disclosed is a method of controlling contamination in such a fuel supply.

    Abstract: The present invention provides a method of monitoring the operation of a radiation source fuel droplet stream generator comprising a fuel-containing capillary and a piezo-electric actuator (500). The method comprises analysing the resonance frequency spectrum of a system comprising the fuel-containing capillary and the piezo-electric actuator in particular to look for changes in the resonance frequencies of the acoustic system which may be indicative of a change in the properties of the system requiring investigation.

    Abstract: An EUV radiation source that includes a fuel supply configured to supply fuel to a plasma formation location. The fuel supply includes a reservoir configured to hold fuel at a temperature that is sufficiently high to maintain the fuel in liquid form, and a pressure vessel configured to contain the reservoir, the pressure vessel being at least partially thermally isolated from the reservoir. The EUV radiation source also includes a laser radiation source configured to irradiate fuel supplied by the fuel supply at the plasma formation location.
