Description
With the ground breaking in July 2017, the construction of FAIR, the Facility for Antiproton and Ion Research, has officially started. Besides the adaption of the existing SIS18 synchrotron for FAIR operation, the ground works for the new SIS100 synchrotron tunnel is presently pursued. FAIR will host four scientific pillars: APPA, CBM, NUSTAR and PANDA. NUSTAR comprises several experiments aiming at the exploration of nuclear structure, astrophysics and reactions at extremes. The exotic ions of interest will be produced by impinging a primary beam of heavy ions (for example uranium) on a target and will be selected by use of the high resolving power of the Super-FRS fragment separator and distributed to three branches: low-energy, high-energy, and the ring branch.
The low energy branch will house the HISPEC/DESPEC experiments dedicated to high-resolution gamma spectroscopy and decay spectroscopy as well as the stopped-beam experiments MATS and LaSpec, which aim at measuring the masses and perform laser spectroscopy on short-lived ions. In the high-energy branch, the R3B collaboration will perform studies on nuclear reactions at high energy and intensity, employing inverse kinematics. The ring branch couples the Super-FRS with the collector ring CR, where the ILIMA collaboration will mount their detectors for mass and lifetime measurements on stored highly-charged short-lived ions. Furthermore, the Super-FRS itself can be employed as a setup for an experiment by adding supplemental detectors at the focal planes of the separator.
Many of the future detectors and equipment are already available and will be used in a precursor phase prior to the operation at FAIR. This program – called Phase 0 – will take place at GSI but also at other facilities, where NUSTAR experimental equipment can be employed for first tests and physics runs.
An overview of the present status of the FAIR facility and the NUSTAR experiments will be given as well as an outlook on the next years of the project.
