Die Strahlungsverluste einesz-Pinches hoher Dichte

The radiative losses of a high densityz-pinch (n _e=10¹⁹cm^?3) were investigated experimentally. When the compressed column has a temperature of 10 eV, the radiative losses were determined by a special measuring method in which the vacuum UV radiation was resolved in time and recorded by means of an open photocell. This method also involved absolute, but time integrated measurement of the radiation by means of a thermopile. It was possible to achieve a certain resolution of the radiation wavelength by filling a volume between the light source and the detectors with various absorbing gases in succession. It was found that the major part of the internal energy of the plasma was lost by radiation.
