Abstract

A sensitive sounding rocket instrument for moderate (~10-A) resolution far-UV (lambda1160-lambda1750-A) spectrophotometry of faint astronomical objects has been developed. The instrument employs a photon-counting microchannel plate imaging detector and a concave grating spectrograph behind a 40-cm Dall-Kirkham telescope. A unique remote-control pointing system, incorporating an SIT vidicon aspect camera, two star trackers, and a tone-encoded command telemetry link, permits the telescope to be oriented to within 5 arc sec of any target for which suitable guide stars can be found. The design, construction, calibration, and flight performance of the instrument are discussed.

摘要

已经研制出一种灵敏的探空火箭仪器，用于对暗弱天体进行中等分辨率（约10埃）的远紫外（波长1160 - 1750埃）分光光度测量。该仪器采用光子计数微通道板成像探测器，并在一台40厘米的多尔 - 柯克汉姆望远镜后面配备了一个凹面光栅摄谱仪。一种独特的遥控指向系统，集成了一个SIT光导摄像管方位相机、两个恒星跟踪器和一个音频编码指令遥测链路，能使望远镜指向任何能找到合适导星的目标，指向精度可达5弧秒以内。文中讨论了该仪器的设计、构造、校准及飞行性能。
