Abstract
Cryogenic cooling by solid cryogens has been utilized in recent years to provide long term instrument cooling in orbit and has demonstrated excellent temperature stability and reliability. Thus far, the solid cryogen system for a given instrument has been specifically developed for each instrument. In an effort to reduce system cost and development time and risk, a study has been conducted to determine the feasibility of a multi-mission cooler. This cooler would have a wide range of application for various instruments and missions and would be reusable and compatible with a variety of cryogens to cover the 10-90°K temperature range. Preliminary design studies have been performed for this system and show the range of application and the characteristics of this cooler. The baseline cooler which evolved utilizes two stages of solid cryogen and incorporates an optional higher temperature third stage which may be cooled by a passive radiator or by other means. An easily adaptable interface is provided which can accommodate a wide variety of instrument configurations through its "drop-in" shrink fit connection.
