The New Experimental Storage Ring NESR

The NESR will be filled with energetic highly-charged heavy ions from SIS18 and with exotic nuclei from the SFRS. At the gas jet target ion-atom reactions as well as the structure of ionized atoms will be studied; x-ray spectroscopy, zero-degree electron spectroscopy, recoil-ion-momentum spectroscopy, and laser spectroscopy will be available. At the electron target the atomic assisted electron-electron interaction will be studied; here also laser techniques and x-ray spectroscopy will support the experiments. At the electron collider electron pulses will interact head-on with laser pulses producing forward emitted x-ray pulses. Moreover, the highly-charged heavy ions can be decelerated in the NESR down to the MeV/u region and extracted toward a fixed target area. There, atomic reactions with highly-charged ions at low velocities will be performed; x-ray spectroscopic and laser techniques will be applied. Connected to the fixed target area will be the HITRAP facility, where ions can be decelerated down to almost rest and captured into a trap system for precision measurements.
