As many of the hydrodynamics experiments carried out are explosively driven, it is important to have blast protection and containment to avoid damage to the facilities and diagnostics. This is often a challenging task, as the detector may only be a few 10s of cm away from the high explosive. It is therefore necessary to have an understanding of structural and fragment modelling. A capability is therefore being developed to predict such behaviour (Figure 1). This work is supported by number of experimental facilities and diagnostics such as open ranges, a Browning powder gun to study fragment penetration (Figure 2), strain and pressure gauges. The vessel currently used to contain some Core Punch experiments is shown (Figure 3). A new vessel is being designed, to contain significant levels of high explosives. Figure 1. Figure 2. Figure 3.
