我们报告的特点和设计细节的中尺度各向异性测量（MSAM），毫米波，球载望远镜，已被用来观察各向异性的宇宙微波背景辐射（CMBR）的0 fdg 5角尺度。座舱能够在一夜飞行期间确定并保持绝对方位至几弧分。重点放在光学和指向性能以及重量和功率预算。我们还讨论了整个气球/吊舱机械系统。来自该系统的摆动是指向系统上的普遍扰动。开发下一代球载仪器需要对这些领域有详细的了解。
We report on the characteristics and design details of the Medium Scale Anisotropy Measurement (MSAM), a millimeter-wave, balloon-borne telescope that has been used to observe anisotropy in the Cosmic Microwave Background Radiation (CMBR) on 0fdg5 angular scales. The gondola is capable of determining and maintaining absolute orientation to a few arcminutes during a one-night flight. Emphasis is placed on the optical and pointing performance as well as the weight and power budgets. We also discuss the total balloon/gondola mechanical system. The pendulation from this system is a ubiquitous perturbation on the pointing system. A detailed understanding in these areas is needed for developing the next generation of balloon-borne instruments.
