Experimental set-up for time-resolved triple-crystal diffractometry. The X-ray beam monochromated by the double-Si(111) monochromator was incident on a GaAs (100) sample wafer. The 400 reflection from the sample was detected through the Si(111) analyzer by a PIN photodiode in photoconductive mode. The output of the photodiode was amplified and then averaged by a digital storage oscilloscope. |
