NUSTARNuclear Structure, Astrophysics, Reactions
NUSTAR is the biggest collaboration in
FAIR
The collaboration unites 450 scientists from 98
institutions of 27 countries.
NUSTAR is a continuation of the research program currently running at GSI where Russian institutes are actively participating.

More than 15 years of collaboration with Russian institutesExisting facilities for studies with exotic nuclei.
γ-spectrometer Crystal Ball
Large-area high-efficiency neutron detector LAND
Large dipole spectrometer ALADIN
Main features of the existing FRS/LAND setup will be preserved in the future R3B setup.
Electron-Ion scattering in a Storage Ring (eA Collider) ELISe
• 125-500 MeV electrons • 200-740 MeV/u RIBs
• achievable luminosity: 1025-1030 cm-2s-1 depending on ion species
- spectrometer setup at the interaction zone
- detection system for RI in the arcs of the NESR (see EXL)
Physics goals
• Charge distribution of exotic nuclei (radius, diffuseness, higher moments...)
req. luminosity: > 1024 cm-2 s-1
• Selective electromagnetic excitationplus spectroscopy, fission, ... studies.Full identification of electric & magnetic multipolarities and of the final state
( new collective soft modes) req. luminosity: about 1028 cm-2 s-1
• Pure electromagnetic probe formfactors F(q) elastic scattering
• F(q) transition formfactors high selectivity to certain multipolarities inelastic scattering
• Large recoil velocities full identification (Z,A) complete kinematics
•Bare ions (no atomic bg.)

Summary and Outlook
• The NUSTAR Facility with the Super-FRS covers a wide range of topics concerning the investigation of exotic nuclei in the areas of: Nuclear Structure, Nuclear Astrophysics, Nuclear Reactions
• NUSTAR will address fundamental questions concerning:
– the Structure und Dynamics of atomic nucleus as many-body system
– the Nature of the effective nucleon-nucleon interaction relevant components, isospin dependence, correlations, EQS of nuclear matter
– Nuclear Astrophysics and the Origin of the Elements• The Super-FRS is part of the first stage of FAIR construction
• There will be a continuous transition from the current FRS program were Russian scientists already actively participating to the future activities at FAIR opening new exciting perspectives
