95 Fig.: Design for the renaming of the high-voltage hall as the Nikola Tesla Laboratory (by Elisabeth Scharinger and Ines Seethaler). The spatial envelope – a cube with bevelled vertical corners – must meet spe- cial technical and physical requirements, in particular the necessary shielding. A technically sophisticated sandwich construction fulfils these requirements. Behind the outer cladding of square corten steel plates with a diamond cuboid surface structure is a densely welded steel construction made of profiled sheets. All cables leading into or out of the hall are routed through special filters so as not to impair this shielding. This makes it possible to produce test voltages of more than one million volts within the hall and simultaneously re- cord signals of the order of one millionth of a volt.
