	New experiments at the planned 'High Energy Storage Ring' (HESR) require magnetised electron cooling. One of the challenges is the powering of the HV-solenoids, because they are located on HV-sections, which sit on an electrical potential inside a high voltage vessel. We discuss a Multi-MV system where the solenoids are powered by a series of cascade transformers which are in turn supplied by turbogenerators. The usage of SF6 as turbine fluid is desirable from the viewpoint of operational stability and may also lead to energy efficient operation of the turboexpanders since a Organic Rankine-cycle (so-called ORC-process) may be used instead of electrically driven compressors. The paper gives an overview of the turbo generator and ORC project: an introduction, a status report and a road map will be given.

For the High Energy Storage Ring (HESR) at FAIR, it is planned to install an electron cooling device with a beam current of 3 A and a beam energy of 8 MeV. A test set-up was built at Helmholtz-Insitut Mainz (HIM) to conduct a feasibility study. One of the main goals of the test set-up is to evaluate the gun design proposed by TSL (Uppsala) with respect to vacuum handling, electric and magnetic fields, and the resulting beam parameters. Another purpose of the set-up is to reduce recuperation losses to less than 10^-5. To measure this quantity and to mitigate collection losses, a Wien filter has been designed and installed. Beam diagnostics will be carried out with a COSY-style beam position monitor. The latest progress of the project is presented.
