Time-resolved nanosecond optical pyrometry of the vapor to plasma transitions in exploding bridgewires

Abstract Electrically exploded wires find uses throughout high-energy physics. For example, they are commonly used as high-temperature sources, X-ray generators, and in precision timing detonators. However, the detailed and complete physics that occurs is complex and still poorly understood. A full...
