Crystalline undulator
WebDec 21, 2001 · One possibility to couple acoustic waves to the crystal is to place a piezo sample atop the crystal and to use radio frequencies to excite oscillations. The usage of a statically and periodically bent crystal was discussed in Ref. [3]. The idea is to construct a crystalline undulator based on graded composition strained layers.

WebOct 11, 2002 · Abstract It is proposed to create crystalline undulators (CU) with periodically deformed crystallographic planes using the curvature due to the alternating stresses arising when strips of very thin films are grown on a thin substrate. WebMay 22, 2024 · The periodic bending gives rise to the spontaneous undulator-type CU radiation (CUR) in the range of wavelengths λ from 0.1 down to 10 −6 Å. Its intensity and characteristic frequencies can be varied by changing the beam energy, the parameters of bending and the type of a crystal.
