thermal shield

thermal shield

[′thər·məl ′shēld]
(nucleonics)
A high-density heat-conducting portion of a shield placed close to the reflector of a nuclear reactor to absorb thermal neutrons, gamma rays, beta rays, and x-rays, whose absorption in the outer shield would generate excessive heat.

InSight's instrument has several ingenious insulating barriers, including a cover built by JPL called the Wind and Thermal Shield, to protect it from the planet's extreme temperature changes and high winds.
The shield, called Wind and Thermal Shield (WTS), enhances the protection of the ultra-sensitive instrument against turbulence caused by wind, sources of additional "noise" disturbing the recording of data.
The three are the seismic experiment for interior structure, the heat flow and physical properties probe, and the seismometer's wind and thermal shield.

A protective vacuum vessel will provide thermal insulation for hundreds of encapsulated cryogenic components that are part of the boxes such as a 80K thermal shield, high temperature superconducting current leads, superconducting busbars, cryogenic coolant circuits with control/safety valves, cold sensors and signal cables, and cold mechanical supports (see diagram).
They first had to design both the scanning probe and the thermal shield compartment in as little space as possible to obtain a small working distance for the SEM.
The extra layer helps control sunlight in the summer, too, and in the winter acts as a thermal shield. It also creates what Olivares refers to as "emotional architecture."
This acts as a thermal shield to deflect heat away from the feet eliminating overheating, and all of the complications related to heat absorption.
