Abstract

A High Rigidity Spectrometer (HRS) has been designed for experiments at the Facility for Rare-Isotope Beams (FRIB) at Michigan State University (MSU). The HRS will allow experiments to be performed with the most exotic neutron-rich isotopes at high beam energies (≳100MeV/u). The HRS consists of an analysis beamline called the High-Transmission Beamline (HTBL) and the spectrometer proper called the Spectrometer Section. The maximum magnetic rigidity of the HRS is 8Tm, which corresponds to the rigidities at which rare-isotope beams are optimally produced at FRIB. The resolving power, angular acceptance, and momentum acceptance are set to match the anticipated scientific program. An ion-optical design developed for the HRS is described in detail, along with the specifications of the associated magnet and detector systems.

The authors are grateful to Dr. Hiromi Sato for his work on the initial magnetostatic and mechanical design of the magnets, and also to the members of the Magnet Design Review group for important suggestions. The science specifications have been devised on the basis of frequent feedback from the members of the HRS Working Group. This material is based upon work supported by the U.S. Department of Energy Office of Science, Office of Nuclear Physics under grant Nos. DE-SC0014554 and DE-SC0000661 (FRIB) and contract No. DE-AC02-06CH11357 (ANL).
