描述了 24m 巨型麦哲伦望远镜 (GMT) 的仪器开发：当前活动、进度、状态和时间表。一个仪器团队已经完成了初步设计，目前正在开始最终设计（GCLEF，一种光学 350-950 nm、高分辨率和精密径向速度中阶梯光栅光谱仪）。第二个仪器团队正处于概念设计阶段（GMACS，光学 350-950 nm、中等分辨率、6-10 arcmin 视场、多目标光谱仪）。第三个仪器团队正处于初步设计阶段（GMTIFS，近红外 YJHK 衍射极限成像仪/积分场摄谱仪）的中期，专注于降低风险原型设计和设计优化。第四个仪器团队目前正在制造开始初步设计阶段所需的 5 个硅浸没光栅（GMTNIRS，同步 JHKLM 高分辨率、AO 馈电、阶梯光栅摄谱仪）。并且，另一个仪器团队专注于技术开发和原型设计（MANIFEST，一种设施机器人，多纤维饲料，具有 20 弧分视野）。此外，中视场（6角分，0.06角秒/像素）光学成像仪将支持望远镜和AO调试活动，并且在窄带成像方面表现出色。本着促进与其他团体协同作用的精神，讨论了运行 ELT 仪器项目的挑战和跨 ELT 合作的机会。
Instrument development for the 24m Giant Magellan Telescope (GMT) is described: current activities, progress, status, and schedule. One instrument team has completed its preliminary design and is currently beginning its final design (GCLEF, an optical 350-950 nm, high-resolution and precision radial velocity echelle spectrograph). A second instrument team is in its conceptual design phase (GMACS, an optical 350-950 nm, medium resolution, 6-10 arcmin field, multi-object spectrograph). A third instrument team is midway through its preliminary design phase (GMTIFS, a near-IR YJHK diffraction-limited imager/integral-field-spectrograph), focused on risk reduction prototyping and design optimization. A fourth instrument team is currently fabricating the 5 silicon immersion gratings needed to begin its preliminary design phase (GMTNIRS, a simultaneous JHKLM high-resolution, AO-fed, echelle spectrograph). And, another instrument team is focusing on technical development and prototyping (MANIFEST, a facility robotic, multifiber feed, with a 20 arcmin field of view). In addition, a medium-field (6 arcmin, 0.06 arcsec/pix) optical imager will support telescope and AO commissioning activities, and will excel at narrow-band imaging. In the spirit of advancing synergies with other groups, the challenges of running an ELT instrument program and opportunities for cross-ELT collaborations are discussed.
