FRIB promises to dramatically expand the variety of nuclear systems
available for direct experimental study by providing rates of many rare
isotopes orders of magnitude higher than those currently available. A new
generation of experimental systems, including new particle spectrometers
will be critical to our ability to take full advantage of the scientific
opportunities offered by FRIB.
The High-Rigidity Spectrometer (HRS) will allow for experiments with the
most neutron-rich and short-lived isotopes produced by in-flight
fragmentation at FRIB. The bending capability of the HRS (8 Tm) matches to
the rigidity for which rare isotopes are produced at the highest intensity
in the FRIB fragment separator. The experimental program will be focused on
nuclear structure and astrophysics, and allow for the use of other
cutting-edge detection systems for gamma, neutron, and charged-particle
detection.
Stopped and reaccelerated beam studies will be an important compliment to
in-flight techniques at FRIB, providing world-unique, high quality, intense
rare isotope beams at low energies up to and beyond the Coulomb
barrier---with the completion of ReA12---and serving many of the science
goals of the broader facility, from nuclear structure and astrophysics to
applications. Two specialized recoil spectrometers are being developed for
studies with reaccelerated beams. SECAR, the Separator for Capture
Reactions, will be built following ReA3, coupled to a windowless gas jet
target, JENSA, and will focus on radiative capture reactions for
astrophysics, particularly those needed to improve our understanding of
novae and X-ray bursts. A recoil separator following ReA12 is proposed to
address a variety of physics cases based on fusion-evaporation, Coulomb
excitation, transfer, and deep-inelastic reactions by providing a large
angular, momentum and charge state acceptance; a high mass resolving power;
and the flexibility to couple to a variety of auxiliary detector systems.
Two designs have been proposed to meet these needs, ISLA, the Isochronous
Separator with Large Acceptance, and an electromagnetic M/Q separator
SUPERB, the Separator for the Unique Products of Experiments with
Radioactive Beams.
