It has a discharge vessel 2, which consists of a central region 3, to which two diametrically opposed bruises 4 are attached.
- the isothermal discharge vessel 2 made of quartz glass, which is a very good approximation, has a wall thickness of approximately 1.8 mm.
- the central region 3 is designed as a spherical body with an outer diameter of approximately 22 mm, so that a discharge volume of approximately 3 cm 3 results.
- the rod-shaped tungsten electrodes 5, the tips of which are 7 mm apart, are each held axially in the pinch 4. They are each surrounded by a molybdenum roller 6, at least in the area of the pinch. The central area has a bulge 7 in the vicinity of the electrodes, which defines the coldest point.
- the bruises 4, which are about 28 mm long are on by means of a short transition zone 11 the central area 3 connected.
- the transition zone 11 is approximately 2 mm long. In it there is a smooth transition between the curved wall the central area and the straight contours of the bruises instead of.
- the radius of curvature in the area of the transition is typically about 2 mm.
- molybdenum foils 12 with a length of 20 mm and a width of 3.5 mm arranged approximately in the middle. They are vacuum tight embedded in the bruise.
- At the distal ends of the Squeezes are formed on cylindrical tube lugs 13 with an outer diameter of 8 mm and an inner diameter of 5 mm.
- the Pipe lugs are each about 10 mm long.
- the electrodes 5 are via the molybdenum foils 12 with external power supplies 14 connected, which is centered on the pipe lugs 13 to the outside extend.
- the power supplies 14 are with metallic base sleeves 15 (see Figure 2) in contact via brazing.
