论文摘要
已经设计了高刚度光谱仪（HRS），用于在密歇根州立大学（MSU）的稀有异位梁（FRIB）的设施中进行实验。 HR将允许在远光灯能量（$ \ gtrsim $ 100mev/u）处使用最奇异的中子同位素进行实验。 HRS由称为高传输光束线（HTBL）的分析梁线和适当称为光谱仪部分的光谱仪组成。 HRS的最大磁性刚度为8tm，对应于稀有 - 同位素束最佳产生的刚性。解决的能力，角度接受和动量接受旨在与预期的科学计划相匹配。详细描述了为HRS开发的离子光设计以及相关磁铁和检测器系统的规格。
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 ($\gtrsim$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.
