Rocking curves of Si 111 diffraction from a channel-cut crystal measured with a 20 µm pinhole and at various beam stops (wire): without a wire, with 0.25 mm, 0.6 mm and 1.0 mm wires. The lens was horizontally configured and the channel-cut crystals were vertically configured. The optical configuration of the XRM is white beam, XPL, wires (with or without), pinhole, channel-cut crystals. |
