A device constructed to generate radiation includes a liquid bath, and a
pair of electrodes. At least a part of one of the electrodes is formed by
a cable part moveable with respect to the liquid bath. The device also
includes an actuator arranged to move the cable part from a
liquid-adhering position to an ignition position, and an ignition source
configured to trigger a discharge produced radiating plasma from the
liquid adherent to the cable part, when the cable part is in the ignition
position, by a discharge between the electrodes. The liquid-adhering
position is a position for adhering a liquid from the bath to the part of
the electrode.
