Aulenbacher, K. Status of the Turbine Concept for Relativistic Electron Coolers JACoW Geneva, Switzerland A turbine driven high voltage section for manetized d.c. electron coolers may offer considerable advantages. This project is pursued in collaboration of BINP and Helmholtzinstitut Mainz. A 600kV prototype has seen first tests and will be installed in a pressurized tank at HIM in 2018. An outlook to further developments will be given.
