A universal setup for kinematical complete measurements of Reactions with Relativistic Radioactive Beams at FAIR — •Thomas Aumann — GSI, Darmstadt

A versatile reaction setup with excellent efficiency, acceptance, and resolution for kinematically complete measurements of reactions with high-energy radioactive beams is proposed. The setup will be located at the focal plane of the high-energy branch of the SUPER-FRS, an integral part of the new accelerator facility FAIR planned at GSI [1]. The setup will be adapted to the highest beam energies (corresponding to 20 Tm magnetic rigidity) provided by the SUPER-FRS. The combination of a superconducting large-acceptance dipole with high-resolution tracking and time-of-flight detectors will provide significant improvements in momentum resolutions for heavy fragments, light-charge particles, and neutrons retaining full-acceptance measurement. An additional magnetic spectrometer allows highest resolution in momentum analysis of heavy fragments. The technical design of the detectors and magnetic spectrometers is presently performed by an international collaboration [2]. The experimental setup is suitable for kinematically complete measurements for a wide variety of scattering experiments, such as heavy-ion induced electromagnetic excitation, knockout and fragmentation, or light-ion (in)elastic and quasi-free scattering in inverse kinematics.
