摘要： A spark gap assembly includes a sealed chamber, at least two discharge electrodes, and a non-radioactive gas fill within the sealed chamber. The sealed chamber includes first and second end plugs and a vitreous tube having opposite ends, each end being sealed by one of said end plugs. The discharge electrodes extend through the first and second end plugs, respectively, from an exposed portion outside of the sealed chamber to an enclosed portion inside the sealed chamber. The discharge electrodes each have a discharge portion that includes a surface from which electrons of a spark discharge exit or are received, with the discharge surfaces of the discharge portions facing each other to thereby define a spark discharge gap between the discharge surfaces of the two discharge electrodes. The gas fill within the sealed chamber includes one or more non-radioactive isotopes of one or more noble gases.

摘要： A spark gap including a capacitive energy store is provided. The spark gap is fed via a multiplicity of capacitors arranged in a form of a ring, wherein the capacitors are electrically connected to the anode and the cathode via ring-shaped and conical or funnel-shaped conductors. As a result, sudden changes in impedance can be avoided. At the same time, it is possible to realize as large a cross-sectional area of the conductor as possible within a very small space. Therefore, the spark gap has a switching response with a high rate of rise of the voltage pulse as soon as the spark gaps flash over. This results in an easily predictable switching response of the spark gap. The spark gap can be used, for example, to generate pulses of monochromatic X-ray radiation.

摘要： A surge arrester comprises an electrical insulator (10), which surrounds a cavity (20), a pin electrode (30) and a tube electrode (40), which are arranged in the cavity (20), wherein the pin electrode (30) projects into the tube electrode (40). An ignition strip (50) is applied on an inner surface (S10a) of the insulator facing the cavity (20). An outer metallization (61, 62, 63) is arranged on an outer surface (S10b) of the insulator (10). As a result, an effective reduction of the protection level can be achieved in the case of the surge arrester.
