Abstract
An apparatus for measuring insulation thermal performance is provided, particularly between ambient and cryogenic temperatures. A warm-temperature boundary has a continuous sample contact surface that is divided into a metered central zone and a boundary guard zone. Each zone is independently heated, and the power necessary to maintain the central zone at constant temperature is directly equated to heat flux through the insulation at the temperature boundary conditions. Methods for measuring insulation thermal performance are also disclosed.
