The 3D Bragg coherent x-ray diffractive imaging involves the measurement of rocking curve scans in the vicinity of Bragg reflections. The counting time at 3rd generation synchrontron is on the order of minutes for 200 nm objects. However, in a lot of cases the particles start to rotate under the beam.
Are there any known good ways to fixate the particles under high fluxes of x-rays (1e11 ph/µm) ?
Thanks!
