摘要:

主焦点摄谱仪(PFS)是一种新的光学/近红外多光纤摄谱仪设计,用于8.2米斯巴鲁望远镜的主焦点。PFS将使用2394根光纤覆盖1.3度直径视野,以补充Hyper SuprimeCam(HSC)的成像能力。PFS的主聚焦单元称为主聚焦仪器(PFI),它提供了与斯巴鲁望远镜顶部结构的接口,还容纳了眼镜蛇光纤定位器所在的光学工作台。此外,采集和引导(A&G)相机、光纤定位器系统、电缆包装、基准光纤、照明器和观察器、现场元件和遥测系统位于PFI内部。PFI的机械结构经过特殊设计,使其偏转与HSC宽视场校正器(WFC)的偏转充分匹配,因此光纤将在所需精度范围内在观测过程中保持在目标上。

英文摘要:

The Prime Focus Spectrograph (PFS) is a new optical/near-infrared multi-fiber spectrograph design for the prime focus of the 8.2m Subaru telescope. PFS will cover 1.3 degree diameter field with 2394 fibers to complement the imaging capability of Hyper SuprimeCam (HSC). The prime focus unit of PFS called Prime Focus Instrument (PFI) provides the interface with the top structure of Subaru telescope and also accommodates the optical bench in which Cobra fiber positioners are located. In addition, the acquisition and guiding (A&G) cameras, the optical fiber positioner system, the cable wrapper, the fiducial fibers, illuminator, and viewer, the field element, and the telemetry system are located inside the PFI. The mechanical structure of the PFI was designed with special care such that its deflections sufficiently match those of the HSC Wide Field Corrector (WFC) so the fibers will stay on targets over the course of the observations within the required accuracy.
