1. An angular pumped and emitting capillary (APEC) discharge light source, comprising: a first electrode having a gas inlet port;  a partially insulating capillary attached to one side of the electrode, having an inlet bore in fluid connection to the gas inlet port of the first electrode, and an outlet bore; and  a second electrode facing the outlet bore of the insulating capillary, wherein applying a voltage between the electrodes causes light to be emitted from the outlet bore of the capillary, and debris formed within the capillary are prevented from exiting the outlet bore of the capillary by the second electrode.  EUV light.  visible light.  ultraviolet light.  vacuum ultraviolet light.  an emitting region having an inwardly angled tapered outlet bore.  a portion facing the outlet bore and having an outwardly tapered surface, so that the radiation is emitted in an angular direction, and the second electrode blocks any debris generated within the capillary from being expelled into collecting optics.  a diameter would range between approximately 0.5 mm and approximately 2.5 mm and an overall length range between approximately 1 mm and approximately 10 mm.  a gap spacing between the second electrode and the outlet bore region less than an interior bore diameter of the capillary.  a tapered surface having an outer diameter larger than an interior bore diameter of the capillary.  a semiconducting material.  a transparent window about the capillary for allowing wavelengths of at least 100 nm to be generated.  a first electrode having a gas inlet port;  a partially insulating capillary attached to one side of the electrode, having an inlet bore in fluid connection to the gas inlet port of the first electrode, and an outlet bore; and  a second electrode adjacent to the capillary; and  a collector means facing the outlet bore of the insulating capillary, wherein applying a voltage between the electrodes causes light to be emitted from the outlet bore of the capillary, and debris formed within the capillary are collected by the collector means.  a first electrode;  a partially insulating capillary attached to one side of the first electrode, having an outlet bore with an emitting region; and  a second electrode adjacent to the capillary;  through-hole means in the capillary for directing inlet gas into the capillary for providing a higher pressure and increasing emission flux in the emitting region; and  a collector-blocking means facing the outlet bore of the insulating capillary, wherein applying a voltage between the electrodes causes light to be emitted from the emitting region of the capillary, and debris formed within the capillary are collected by the collector means.  a first electrode having a conduit for introducing an emitting gas therethrough;  a second electrode spaced apart by a gap to the first electrode, wherein applying a voltage to the first electrode and the second electrode forms an emitting region in the gap so that the second electrode serves to block and collect electrode debris material; and  means for pumping gas away from the emitting region so as to provide a low pressure for transmission of EUV flux. 2.
