Improved Design of EURISOL Fission Target Systems and Handling

The report discusses the constraints, solutions and options for integration of the main systems needed to assure the operation and maintenance/exchange of the fission target – ion sources assemblies capable to withstand very high neutron fluxes around EURISOL multi-MW neutron converter, to provide the desired fission rate of 10e15 fis./sec. and to extract with highest possible efficiencies the fission products as radioactive ion beam. Adapting the concepts developed for a single fission target within PIAFE and MAFF projects, simultaneous operation of six fission targets was proposed for EURISOL. A first design following these concepts was presented in a previous report. Here we describe several improvements implemented in the design for a more efficient, more reliable and safer operation. An optimized layout of the part of the EURISOL MMW station related to fission target services and handling is proposed as well
