Abstract : This report details various experimental techniques for imaging the detonation wave in chemically sensitised nitromethane and their application towards developing a rim initiating waveshaper for reliable and symmetric cylindrical convergence of the detonation wave. A Cordin high speed camera was used for the imaging and two successful techniques were developed; direct imaging of the light given off by the detonation wave, and imaging of the pressure wave through adiabatic compression of a small air gap underneath the charge. Modifications to the waveshaper to ensure correct performance are presented and analysed with the imaging techniques developed.
