Shock focusing allows for concentration of energy in a specific area, and the creation of localized extreme conditions such as high temperature and pressure. Shock waves can undergo either regular or irregular reflections. The type of reflection generated significantly changes the properties behind the shock front. In order to obtain a high degree of control over the shock front, the parameters of regular and irregular reflections, and their respective transition criterion must be understood. Particularly, the relationship between the shape of the shock and the properties behind the shock front are of interest. In this study, experiments were conducted using an exploding wire setup for producing two synchronized shock waves. Exploding wire setups provide rapid experiment iteration and exceptional cost effectiveness compared to large-scale experiments or computational modeling. The data used for shock-shock interactions was collected via pressure sensors and ultra high-speed schlieren imaging. Experiments exhibited a high degree of Title repeatability, which allowed for the comparison of the peak pressures of the Mach be compared to that of the incident shock. It was concluded that the Mach stem exhibits peak pressures that are on average 24.92%±8.54% greater than the peak pressures of the incident shock, but decay faster. It was also determined that Mach reflection were only seen in cases where the Mach number exceeds approximately 1.45.
