description: A new electron target section (ETS) as a dedicated electron target for the storage ring TSR has been mounted and tested. With the help of this device electron collision experiments on a stored ion beam can be performed independently of the phase space cooling (electron cooling) of this beam. Preparatory measurements to study the adiabatic magnetic expansion and the adiabatic acceleration of the electrons have been performed on this device. Longitudinal energy spreads where studied in dependence of several parameters using the installed retarding field energy analyzer. The operation of the ETS together with the existing electron cooler device could be demonstrated in a storage ring experiment. An interaction of the continuously cooled stored ion beam with the electron target beam could be studied. A dielectronic recombination resonance in lithium-like fluorine F/sup 6+/ was used to determine the longitudinal and transverse electron temperature. An improvement of the energy resolution compared to earlier measurements with the electron cooling device as target could be demonstrated.
