Experimental XAFS arrangements for testing the performance of the beam cleaner selecting the second harmonic (3× fundamental). (a) Reference arrangement, (b) includes an aluminium filter to select the harmonic by blocking the fundamental, (c) includes a thick aluminium attenuator to simulate a thick sample, (d) shows the beam cleaner selecting the second harmonic [to be compared with the arrangement in (b)], and (e) shows the cleaner with the aluminium attenuator [to be compared with the arrangement in (c)]. |
