    摘要: The invention is directed to an arrangement for the generation of short-wavelength radiation based on a hot plasma generated by gas discharge and to a method for the production of coolant-carrying electrode housings. It is the object of the invention to find a novel possibility for gas discharge based short-wavelength radiation sources with high average radiation output in quasi-continuous discharge operation by which efficient cooling principles can be implemented using inexpensive and simple means in order to prevent a temporary melting of the electrode surfaces and, therefore, to ensure a long lifetime of the electrodes. According to the invention, this object is met in that special cooling channels for circulating coolant are integrated in electrode collars of the electrode housings. The cooling channels are advanced radially up to within a few millimeters of the highly thermally stressed surface regions and are connected by necked-down channel portions which are arranged coaxial to the axis of symmetry and which are provided with channel structures for increasing the inner surface and for increasing the flow rate of the coolant.

    摘要: The arrangement for generating EUV radiation based on electrically triggered gas discharges with high repetition rates and high average outputs. The object of the invention, to find a novel possibility for generating EUV radiation based on a gas discharge pumped plasma which permits the generation of EUV pulse sequences with a pulse repetition frequency of greater than 5 kHz at pulse energies of at least 10 mJ/sr without having to tolerate increased electrode wear, is met according to the invention in that a plurality of source modules of identical construction, each of which generates a radiation-emitting plasma and has bundled EUV radiation, are arranged in a vacuum chamber so as to be uniformly distributed around an optical axis of the source in its entirety in order to provide successive radiation pulses at a point on the optical axis, so that a reflector device which is supported so as to be rotatable around the optical axis deflects the radiation delivered by the source modules in the direction of the optical axis successively with respect to time. A synchronization device triggers the source modules in a circularly successive manner depending upon the actual rotational position of the reflector device and adjusts a preselected pulse repetition frequency by means of the rotating speed.

    摘要: The invention is directed to a method for the energy stabilization of a gas discharge-pumped radiation source that is operated in defined pulse sequences, particularly for suppression of overshooting and undershooting of excimer lasers and EUV radiation sources in burst operation. It is the object of the invention to find a novel possibility for the stabilization of the energy emission of a gas discharge-pumped radiation source that is operated in defined pulse sequences (bursts) which makes it possible to take into account a temporary behavior of the radiation source at the beginning of every burst without repeated recalibration of the energy-voltage curve. In a method with proportional regulation of the charging voltage as a function of the measured pulse energy, the object stated above is met according to the invention in that the pulse energy En(p) to be adjusted for a current pulse in the current burst is calculated from the pulse energy of the preceding pulse in the current burst and an identical pulse En(p-1) of a preceding precursor burst, wherein the precursor burst is an unregulated model burst and the high voltage which is to be adjusted currently for the current pulse is calculated from the current pulse energy En(p) by dividing by the rise dE/dU of the function of the pulse energy depending on the charging voltage in the linear operating range of the radiation source.
