ABSTRACT:
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.
