Abstract

A far-infrared radiometer, cooled to 1.6 K by superfluid helium, has been flown in a Terrier-Sandhawk rocket. The instrument was designed to measure night-sky radiation in three wavelength passbands between 6 mm and 0.1 mm at altitudes between 120 km and 350 km. A failure in the rocket nose cone separation system prevented the measurement of this radiation, but the performance of the instrument during flight was generally satisfactory. Design features and operational characteristics of the cryogenic, optical, detection, and electronic systems are presented.

摘要

一台由超流氦冷却至1.6 K的远红外辐射计搭乘“小猎犬-沙鹰”火箭进行了飞行。该仪器旨在测量120千米至350千米高度之间6毫米至0.1毫米三个波长通带的夜空辐射。火箭鼻锥分离系统故障导致无法进行这种辐射的测量，但仪器在飞行过程中的性能总体令人满意。文中介绍了低温、光学、探测和电子系统的设计特点及运行特性。
