| Abstract |
A transverse electron target already constructed is under investigation for the application in storage rings at the FAIR facility. Using a sheet beam of free electrons in a crossed beam geometry promises a high energy resolution and gives access to the interaction region for spectroscopy. The produced electron beam has a length of 10 cm in ion beam direction and a width of 5 mm in the interaction region with electron densities of up to 10⁹ electrons/cm³. The target allows the adjustment of the electron beam current and energy in the region of several 10 eV and a few keV. Simulations have been performed regarding the energy resolution for electron-ion collisions. Also the ion optical behaviour of the target was investigated numerically. The target is integrated in a test bench to study the performance of the electron gun and the electron beam optics. The installed volume ion source delivers light ions and molecules for characterization of the target performance by measuring charge changing processes. Subsequently the target will be installed temporarily at the Frankfurt Low-Energy Storage Ring (FLSR) for further test measurements. An overview of the project status will be presented.
