Measurement of rocking curves of crystals using an acoustically tunable monochromator

A new scheme for measuring rocking curves (RCs) based on a previously proposed method for measuring RCs using an X-ray-acoustic analyzer crystal has been developed and implemented. In this scheme, this analyzer crystal is applied as a tunable monochromator, mounted directly after the X-ray source. This new experimental scheme has a number of significant advantages in comparison with the previously proposed scheme. The new scheme is approved and its potential is estimated.
