Aerogels tiles

Figure 7 Directional-hemispherical solar transmission tdh as a function of density p for different aerogels granular aerogel (diamond) low-density aerogel tiles from LLNL (L. W. Hrubesh, squares) aerogel tiles from DESY, Hamburg (G. Poelz, filled circles) specimens made by P. Wang (University of Wiirzburg) at pH 13 (open circles) and pH 11 (asterisks). Thickness of all specimens was 20 mm.

Figure 23.22. Measured and calculated thermal conductance A as a function of 7 for a silica aerogel tile with a density of 50 kg and a thickness d of 6.7 mm [47], The measurements were performed under different atmospheres and with two different boundary emissivities (0.04 blue symbols, 0.1 A red symbols).

A typical single threshold-type aerogel Cherenkov counter (ACC) module looks as shown in Figure 28.12. TMSA tiles are stacked in a thin aluminum box of approximate dimensions 120 x 120 x 120 mm. In order to detect the Cherenkov light effectively, two fine mesh-type PMTs are attached directly to the aerogels at both sides of the box. The inner surface of the box (except for the phototube windows) is lined with a diffuse reflector...
