Description
It is planned to install a ribbon-shaped high-density free-electron
target in the experimental section of the presently being
commissioned storage ring CRYRING@ESR of the upcoming Facility for
Anti-proton and Ion Research (FAIR) [M. Lestinsky et al., Eur.
Phys. J Spec. Top. 225, 797 (2016)]. Electron beam and circulating
stored ion beam interact under an angle of 90°. Recently, we have
developed a new versatile electron gun with electron energies up to
12.5 keV which is optimized for the storage ring environment as
well as for photon spectroscopy. This gun is presently built as
well as the entire target station. In this contribution we present
the physics opportunities of such a free-electron target at a
heavy-ion storage ring and give an overview about the present
status of the project.
