    • x-ray reflectometry one can usually do further fine tuning by using the absorption of x-rays by the sample: First one sets the spectrometer to detect the direct through going beam. Then the sample is translated until it blocks half of the direct beam. Subsequently, the sample is rotated to have a minimum blockage, corresponding to a position parallel to the direct beam. These last two steps are repeated until they converge. This procedure works only if the sample strongly absorbs the beam, which is usually not the case with neutrons, for which many samples are transparent
