Schematic diagram of a cylindrical charge with sand above the flight tube, sacrificial materials glass and iron powder, light blue area outlined in red in the centre: evacuated area The basic principle of the cylindrical test arrangement is the same as for the planar arrangement: a metal object is accelerated by the detonation of an explosive and collides with the sample container. With the flyer-tube, the geometry is changed so that a hollow tube (instead of a plate) is accelerated from the outside onto an internal cylinder containing the sample.
- only single-shock (simple pressure build-up)
- no impedance correction and no control of adiabatic decompression (lower reproducibility)
- larger sample volumes possible (currently 40 cm3 sample volume, upscaling to dm3 range possible)
- evacuation of the areas inside the flyer tube possible
