Karlsruhe Nuclear System

Microanalysis systems which are built up in a modular way can be adapted to various applications by exchanging individual modules. Thus, a bigger number of units can be sold and prices reduced. At the Karlsruhe Nuclear Research Center a microfluidic handling module is being developed which will be used in two different microanalysis systems joined with sensor modules. A batch fabrication process has been developed which was used to manufacture micropumps and microvalve systems by assembly of two molded thermoplastic parts and transfer of a polyimide diaphragm from a silicon wafer. 

The most complete phase studies have been carried out on LiF-RFs and NaF-RFs systems in 1960-1970. This interest was mainly based on their importance in Molten-Salt Reactor Programs (e.g. Thoma and co-workers at Oak Ridge National Laboratory, USA Keller and Schmutz of the Society of Nuclear Research in Karlsruhe, West Germany). Furthermore, some of the intermediate phases are suitable as host lattices for lasers, e.g. A(R R )F4, and up-conversion materials, e.g. A(R R R")F4. Magnetic properties of ARF4 phases have also been studied and are reviewed in the Gmelin Handbook (1976). A few NaRF4 phases show fluorescence after irradiation with cathodic rays.
