DEBYE-SCHERRER X-ray powder patterns are conventionally obtained on photographic emulsions in times of the order of hours. When special techniques are used, the time required can be reduced to minutes ...
Figure 1: a) Stationary diffraction pattern of cBN powder, integrated over the Debye-Scherrer rings, measured with femtosecond x-ray pulses as a function of the diffraction angle 2θ. b) Transient ...
