(a) 3 mm-thick Si asymmetric crystals with 444 reflection, mounted in the double-axis diffractometer for the EAT measurements. Both the forward-diffracted o-beam and the diffracted h-beam were measured by scintillation detectors. (b) Measured forward-diffracted o-beam (open red circles) and diffracted h-beam (open black circles) profiles. |
