Experimental set-up for measuring lattice constants. X-rays after a high-heat-load monochromator (not shown) pass through the vertical slits S1 and S2 at a distance of 26.6 m. : -meter; F: 57Fe foil used as a source of Mössbauer radiation of high brightness; D: semi-transparent avalanche photodiode with 0.7 ns time resolution; Al2O3: sapphire single crystal in a furnace on a four-circle goniometer. |
