X-ray Optics - Studentportalen
... In the hard X-ray range it is easy to find scattering plane where this condition is fulfilled. Here one also uses that the penetration length of the photons are large, so that many crystal planes contribute to the scattering: thus the resolving power can become very large. At ESRF (ID16 and ID28) on ...
