Abstract

This paper describes the test methodology and designs used to accurately and deterministically test and measure the thermal performance of the JWST 'core' region. The core region of JWST is between the warm spacecraft and the cold telescope. This complex region represents much of the thermal performance uncertainty to the largely passively cooled observatory. Specific topics include q-metering, q-targeting, dark enclosures, sensitivity and uncertainty analyses.
