Each year approximately 99% by mass of energetic material use takes place in the quarrying, mining, construction and petrochemical industries. The coupling of explosively driven shock waves to heterogeneous geological materials is of scientific and industrial relevance. Here we report the first experiments conducted with energetic materials at the ID19 beamline at the European Synchrotron Research Facility, Grenoble, France. The experiments used commercial detonators to explosively load sand samples and glass spheres. Time resolved images showing the compaction wave produced by the explosive loading of both coarse- and fine-grained sand as well as large and small diameter glass spheres. [ABSTRACT FROM AUTHOR]

We present a double multilayer monochromator (DMM) design which has been realized for the BAMline (BESSY-II light source, Germany) as well as in an updated version for the TopoTomo beamline (ANKA light source. Germany) [1–4]. The latter contains two pairs of multilayer stripes in order to avoid absorption edges of the coating material. For both DMMs, the second multilayer offers a meridional bending option for beam compression to increase the available photon flux density. Each multilayer mirror is equipped with a vertical stage for height adjustments allowing for compensation of varying incoming beam heights and giving a certain flexibility choosing the offset. The second multilayer can be moved in the beam direction in order to cover the full energy range available. Furthermore, a white beam option is available. [ABSTRACT FROM AUTHOR]
