    摘要： A spark gap switch apparatus is disclosed which is capable of operating at a high pulse rate which comprises an insulated housing; a pair of spaced apart electrodes each having one end thereof within a first bore formed in the housing and defining a spark gap therebetween; a pressure wave reflector in the first bore in the housing and spaced from the spark gap and capable of admitting purge flow; and a second enlarged bore contiguous with the first bore and spaced from the opposite side of the spark gap; whereby pressure waves generated during discharge of a spark across the spark gap will reflect off the wave reflector and back from the enlarged bore to the spark gap to clear from the spark gap hot gases residues generated during the discharge and simultaneously restore the gas density and pressure in the spark gap to its initial value.

    摘要： An irradiation device includes: a light source having an amalgam alloy member that is disposed on a part of the inner surface of a light source tube; and a chamber in which the light source is disposed. The chamber includes: a main chamber body; and a first gas inflow port and a first gas outflow port that are formed in the main chamber body. The first gas inflow port and the first gas outflow port are arranged so that the outer surface of the part of the light source tube where the amalgam alloy member is disposed is positioned in a flow path of a gas that flows in through the first gas inflow port and flows out through the first gas outflow port.

    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.
