Ionenstrahlätzen – Verfahren und Ausrüstungen für die Mikrostrukturierung

Ion beam techniques are widely used jur modification as well us analysis of materials in development and production of VLSI circuits and their importance is continuously increased in course of the reduction of structure dimensions. Some possibilities and problems connected with the application of ion beams of low energy in the pattern transfer are- described and the stage of development achieved in the Central Institute of Isotope and Radiation Research is outlined.

Retrospective evaluation of occupational annual doses received by workers producing radioactive sources

Personal dosimetric data from external radiation recorded during a 19-year period at the Institute of Isotopes were subjected to extensive computer analysis to examine the applications of the relevant ICRP dose limitation system by following the trend of radiation exposures and estimating the risk levels for various occupational fields.

Distributed Data Processing System for Laboratory Automation with ESER Computer and Several Experiment Computers

Communication between a central computer ROBOTRON ES 1040 and remote experiment computers at the Leipzig Central Institute of Isotope and Radiation Research is presented. It is a multi-user real-time computer network with hierarchical structure.
