Abstract

SuperBIT was a 0.5-meter near-ultraviolet to near-infrared wide-field telescope that launched on a NASA superpressure balloon into the stratosphere from New Zealand for a 45-night flight. SuperBIT acquired multi-band images of galaxy clusters to study the properties of dark matter using weak gravitational lensing. We provide an overview of the instrument and its various subsystems. We then present the instrument performance from the flight, including the telescope and image stabilization system, the optical system, the power system, and the thermal system. SuperBIT successfully met the instrument's technical requirements, achieving a telescope pointing stability of 0.34 +/- 0.10 arcseconds, a focal plane image stability of 0.055 +/- 0.027 arcseconds, and a PSF FWHM of ~ 0.35 arcseconds over 5-minute exposures throughout the 45-night flight. The telescope achieved a near-diffraction limited point-spread function in all three science bands (u, b, and g). SuperBIT served as a pathfinder to the GigaBIT observatory, which will be a 1.34-meter near-ultraviolet to near-infrared balloon-borne telescope.

SuperBIT 超压飞行仪器概述和性能:来自平流层的近衍射极限天文成像
SuperBIT 是一个 0.5 米的近紫外至近红外宽视场望远镜,它搭载在美国航天局的一个超压气球上,从新西兰发射到平流层,进行了 45 夜的飞行。SuperBIT 获取了星系团的多波段图像,利用弱引力感应研究暗物质的特性。我们概述了仪器及其各个子系统,然后介绍了飞行中的仪器性能,包括望远镜和图像稳定系统、光学系统、电源系统和热系统。SuperBIT 成功地满足了仪器的技术要求,在整个 45 夜的飞行中,望远镜的指向稳定性达到了 0.34 +/- 0.10 弧秒,焦平面图像稳定性达到了 0.055 +/- 0.027 弧秒,在 5 分钟的曝光中,PSF 的 FWHM 达到了 ~ 0.35 弧秒。该望远镜在所有三个科学波段(u、b 和 g)中都实现了接近衍射限制的点展宽函数。SuperBIT 是 GigaBIT 观测站的探路者,GigaBIT 观测站将是一个 1.34 米的近紫外和穿透红外气球式望远镜。
