	One challenge in the development of a relativistic electron cooler is the powering of components, e.g. HV-solenoids, which sit on different potentials within a high voltage vessel and need a floating power supply. Within a design study, BINP SB RAS Novosibirsk has proposed two possibilities to build a power supply in a modular way. The first proposal is to use two cascade transformers per module. One cascade transformer powers 22 small HV-solenoids; the second one should generate the acceleration/deceleration voltage. The cascade transformers are fed by a turbo generator, which is powered by a gas under high pressure which is generated outside of the vessel. The second possibility is to use two big HV-solenoids per module. In this proposal, the HV-solenoids are powered directly by a turbo generator. For both concepts, a suitable turbo generator is essential. A potential candidate for the turbo generator could be the Green Energy Turbine (GET) from the company DEPRAG, which works with dry air and delivers a power of 5 kW. At the Helmholtz-Institut Mainz two GETS are tested. After an introduction, we present our experience with the GET and give an overview of the further road map.

	A high efficiency electron collector for the COSY high voltage electron cooling system was developed. The main feature of the collector is usage of special insertion (Wien filter) before the main collector, which deflects secondary electron flux to special secondary collector, preventing them fly to the electrostatic tube. In first tests of the collector in COSY cooler efficiency of recuperation better then 10^-5 was reached. Before assembling of the cooler in Jülich upgrades of the collector and electron gun were made. After the upgrade efficiency better then 10-6 was reached. Design and testing results of the collector are described.
