[en] The cooperation between IPP and IPF in the field of fusion related research and development has been successfully continued. The ECRH-activities were mainly concentrated on the construction of the 70 GHz-facility for the W VII-AS-stellarator and the development of new components for the transmission and measurement of millimetre waves. Theoretical calculations have been concerned with numerical plasma simulations and wave propagations. The LIDAR Thomson-scattering arrangement was successfully operated on JET and, as well, a great deal of progress has been made with the far infrared scattering on ASDEX. The flux-surface measurements on WEGA using electron-beams with a new improved detection system achieved excellent results. The plasma-focus experiments were continued. The neutron yield could be increased by a factor of two. Plasma-technology activities have demonstrated initial success. (orig.)
