Thesis. Submitted to Bochum Univ. (West Germany). It was shown that the radiation emitted during the dense phase of a plasma focus cannot be explained by the radiation theory valid for two-particle collisions, but that collective effects must be assumed which lead to the observed nonthermal radiation of the plasma. The radiation found can be explained as radiation with the double plasma frequency. It is conceivable that the plasma focus, besides its property as an economical pulsed neutron source, can be used as a light source of extremely strong intensity in the longwave spectral range. The nonthermal and thermal intensity of the plasma focus can be increased by a factor of 2 to 3 by choosing another electrode material, e.g., copper. The intensity of the thermal radiation is dependent on the square of the atomic number. If one could control and change the percentage of heavy ions in the plasma, then the dependence of the nonthermal radiation on the atomic number could be determined. (GE)
