One of the challenges in a relativistic electron cooler is the generation of high voltage exceeding 2 MV and the powering of HV-solenoids, which need a floating power supply. As replacement of the well established, but limited, methods we propose streaming gas for the power transfer. The conversion of the energy by a turbo generator enables using scalable power supply / HV-generator combinations. BINP SB RAS has proposed two possibilities to build the power supply in a modular way. In the first

In order to reach the final voltage, the modules are cascaded. The cascade transformers are fed by a turbo generator, which is driven by pressurised gas. The second possibility is to use two big HV-solenoids, which are powered directly by a turbo generator. The voltage could be generated for example with a Cockcroft Walton generator. A potential candidate is the Green Energy Turbine (GET) from the company DEPRAG, Germany. At the Helmholtz-Institut Mainz, two GET were tested. In this report, we present our experience and show first results.
