The R3B experiment at FAIR — •Heiko Scheit — TU Darmstadt
The experiment Reactions with Relativistic Radioactive Beams (R3B) at the FAIR facility will be installed at the high-energy branch of the Super-FRS. It allows for kinematically complete nuclear reaction studies with short-lived radioactive ion beams in inverse kinematics, utilizing a wide beam energy range from about 100–1000 MeV/u covering the full mass range up to uranium. Experimental programs will address fundamental questions in nuclear structure and reaction physics, as well as nuclear astrophysics.
Recently, after a long research and development phase, important milestones toward the realization of the R3B experiment have been reached with the completion of the technical design reports for two core components of the R3B setup: the NeuLAND high-resolution neutron time-of-flight spectrometer and the CALIFA Barrel, which serves as a γ-ray spectrometer, calorimeter and, together with the Si-tracker, as a target-recoil detector. In addition, the construction of the superconducting large-acceptance dipole magnet R3B-GLAD, used for the magnetic rigidity analysis of beam-rapidity charged fragments, is well underway with an expected delivery at GSI in summer 2013.
First commissioning and physics experiments at GSI with R3B-GLAD and 20%-versions of NeuLAND and the CALIFA Barrel will be carried out in 2014. Until 2016 the setup will be largely completed at GSI and moved to the new high-energy cave at FAIR in 2017/8.
I will give an update on the current status of the project.
