The dynamical diffraction from bent crystals has been a topic of numerous studies over decades (Penning & Polder, 1961 ▸ Kato, 1964 ▸ Bonse, 1964 ▸ Chukhovskii & Petrashen’, 1977 ▸ Chukhovskii et al., 1978 ▸ Kalman & Weissmann, 1983 ▸ Gronkowski & Malgrange, 1984 ▸ Chukhovskii & Malgrange, 1989 ▸ Gronkowski, 1991 ▸ Honkanen et al., 2018 ▸).
Bent single crystals are commonly used as the X-ray optic elements for beam conditioning as well as the analysers for X-ray spectroscopy.
