Component for exposing fluid to an input shockwave

A component 5 suitable for exposing fluid to an input shockwave. The component 5 comprises a body 7 defining an input face 17 arranged to receive the input shockwave. The body 7 further comprises a chamber 21 recessed in the input face 17 suitable for containing fluid, a fluid inlet 11 for introducing fluid into the component 5, and an intermediate volume 15 defined in the input face 17. The intermediate volume 15 is provided at least partially between the fluid inlet 11 and the chamber 21. The intermediate volume 15 is fluidly connected to the fluid inlet 11 and to the chamber 21 for supplying fluid from the fluid inlet 11 to the chamber 21. A portion of the input face 17 is configured to sealingly abut against a further element 3 for enclosing the intermediate volume 15.
