摘要： The present invention relates to a method and device for generating optical radiation, in particular EUV radiation or soft x-rays, by means of an electrically operated discharge. A plasma (15) is ignited in a gaseous medium between at least two electrodes (1, 2), wherein said gaseous medium is produced at least partly from a liquid material (6) which is applied to a surface moving in the discharge space and is at least partially evaporated by one or several pulsed energy beams. In the proposed method and device the pulses (9) of said pulsed energy beams are directed to at least two different lateral locations with respect to a moving direction of said surface. With this measure, the radiation emission volume is expanded, less sensitive to spatial fluctuations and can be adapted better to the requirements of optical systems of any applications. Furthermore, the optical output power can be increased by this measure.

摘要： The present invention relates to a method of operating an electrical discharge device (12) comprising at least one first electrode (14) and at least one second electrode (16) at a distance therefrom, which electrodes are electrically connected to a power supply (18) and, upon ignition of a first gas discharge (22) between the electrodes (14, 16), transmit an electrical current (I), as a result of which a plasma (24) is produced in a working gas (26), which plasma emits radiation (28), in particular extreme ultraviolet and/or soft X-ray radiation, which is passed via a solid angle (30) into a chamber (32) outside the electrodes (14, 16). In order to prevent erosion at the electrodes (14, 16), it is proposed that the formation of a secondary plasma (34) in the chamber (32) is suppressed by a device (42).

摘要： Process and device for operating an internal combustion engine with less pollutant emission, whose exhaust gas is subjected to an electrical aftertreatment during engine operation to convert pollutants, the emissions of which are measured. To improve a process with the features mentioned initially, so that on the one hand the desired reduction of emissions of the internal combustion engine is achieved during its entire time of operation, but on the other hand so that the design of the electrical system of the internal combustion engine does not have to be unreasonably large and thus costly, the electrical aftertreatment of the exhaust gas occurs only during the portion of the operating time during which emission peaks occur.

摘要： The invention is an improvement in a device for generating X-radiation with a plasma source. In the device, two concentric cylindrical electrodes (11, 12) are separated by an evacuated discharge space (13) filled with low-pressure gas. When the inner electrode is momentarily raised to an extremely high voltage, the gas is ionized and a plasma shock wave (17, 17') is created and compressed into a plasma focus (21) emitting X-radiation (20). The improvement introduces a first ("discharge") gas into the discharge space for initiation of the plasma, while introducing a second ("emitting") gas into the inner electrode for generating the X-radiation in the plasma focus. Special features of the improved device include a plurality of gas extraction ports, which can be used independently or together, and which can be combined with variations in the introduction and flow of the two gases to control the movement and intermixture of the gases and, thereby, the operation of the device. Also, the device introduces a third gas for improving the transmission of the X-radiation from the generating plasma focus to a work station for X-ray microscopy or for X-ray lithography.
