Strong multiple Bragg reflections (MBRs) which can be realized in a bent-perfect-crystal (BPC) slab provide a monochromatic beam of excellent resolution parameters. For identifying MBR effects in the BPC Si crystal, we used the method of azimuthal ro

A new type of dispersive monochromator based on the double reflection process realized between two bent perfect crystal slabs attached in the form of a sandwich. The dispersive sandwich monochromator/analyzer provides a freedom to combine crystal sla
