Coherent X-ray diffraction imaging (CXDI) is a lens-less imaging technique that visualizes the structures
of non-crystalline particles with micro- to sub-micrometer dimensions. In CXDI experiments, single
spatially isolated particles are irradiated by X-ray beam with high transverse coherence. The projection
images of the particles along the incident X-ray direction are then directly reconstructed from the
diffraction amplitude using a phase retrieval algorithm. We recently developed a sample preparation
system operated under a moisture controlled condition and a diffractometer to conduct cryogenic CXDI
experiments at SPring-8 and the X-ray free electron laser (XFEL) facility called SACLA. Here we
briefl y introduce the theoretical background and show the preliminary experimental data from samples
prepared by the humidity-control system collected with the diffractometer at BL29XU of SPring-8 and
the BL3 of SACLA.
