A free-electron target for the ion-storage rings at FAIR: current status — Carsten Brandau1,2, Alexander Borovik Jr1, •B. Michel Döhring1,2, Benjamin Ebinger1,2, and Stefan Schippers1 — 1Justus-Liebig-Universität Gießen — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt (Germany)
The Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is presently under construction and will provide worldwide unique possibilities for heavy-ion research. For the investigation of electron-ion collisions, a free-electron target is presently built [1]. It will be installed initially at the low-energy ring CRYRING@ESR but can also easily be adapted to the other heavy-ion storage rings of FAIR. The electron target will operate in 90 degrees geometry between ion and a ribbon-shaped electron beam. The electrode geometry has been designed such that a large part of the well localized electron-ion interaction region can be easily accessed by x-ray and electron spectrometers under large solid angles. We will summarize the physics, the concept and the present status of the project.
