FACILITIES FOR STUDYING IR DEVICES AT A LOW RADIATIVE BACKGROUND LEVEL

This paper describes and presents the main characteristics of a series of simulation-measurement facilities for studying IR photodetectors a nd telescopes under conditions of low-level background irradiation. It shows that multifunctional studies of IR devices are possible on appa ratus based on a modular arrangement of separate deeply cooled simulat ion and diagnostic systems. Along with sufficient completeness of the characteristics being studied, this apparatus excels other existing ap paratus of this class in most economical indicators, including capital cost, energy consumption, etc.
