	The 2 MeV electron cooling system for COSY-Juelich was proposed to further boost the luminosity even in presence of strong heating effects of high-density internal targets. The project is funded since mid 2009. Manufacturing of the cooler components has already begun. The space required for the 2 MeV cooler is being made available in the COSY ring. The design and construction of the cooler is accomplished in cooperation with the Budker Institute of Nuclear Physics in Novosibirsk, Russia. The 2 MeV cooler is also well suited in the start up phase of the High Energy Storage Ring (HESR) at FAIR in Darmstadt. It can be used for beam cooling at injection energy and is intended to test new features of the high energy electron cooler for HESR. The technical layout of the 2 MeV electron cooler is described and the status of component manufacturing is reported.

	Electrostatic storage rings have proven to be invaluable tools for atomic and molecular physics at the ultra-low energy range from 1 to 100 keV/A. Due to the mass independence of the electrostastic rigidity, these machines are able to store a wide range of different particles, from light ions to heavy singly charged bio-molecules. Reaction Microscope incorporated into a ring lattice is considered to be a new powerful tool to study high precision effects by multiple crossing of incident beam of ions with ultrasonic gas jet. To enable operation of Reaction Microscope one should provide very short bunches in the 1-2 nanosecond regime in order to pave the way for kinematically complete measurements of the collision dynamics of fundamental few-body quantum systems on the level of differential cross sections. However, earlier measurements at some rings showed strong limitations depending on beam intensity, probably linked to non-linear fields that cannot be completely avoided in such machines. In this contribution, we discuss common features of electrostatic storage rings and analyse rings performance.
