    Abstract: A dewar (20) includes an inner dewar (22) and a dewar thermal shield (24). The dewar thermal shield (24) has a thermal shield body (32) formed of a layer of radiative insulation, an inner layer of fiberglass cloth (102) overlying the layer of radiative insulation (100), a metallic screen (104) overlying the inner layer (102), and an outer layer (106) of fiberglass cloth overlying the metallic screen (104). The dewar thermal shield (24) also has a thermal shield tail cap (34) attached to the thermal shield body (32). The tail cap (34) is formed of a layer of radiative insulation (50), a layer of fiberglass cloth (51) overlying the layer of radiative insulation (50), a layer of thermal foil (52) overlying the layer of fiberglass cloth (51), the thermal foil (52) being formed of thermal conductors embedded in a film adhesive matrix with the thermal conductors extending to the body (32), and a top layer of fiberglass cloth (54) overlying the layer of thermal foil (52).
