An experimental study was directed toward gaining improved understanding of the exact mechanisms causing ignition in the ptb (cadmium disk) breakflash. Tungsten and copper wires were investigated and compared as to their ability to cause hot wire ignition. The importance of discharge duration in the ignition process was evaluated. The parameters influencing the duration of a discharge (minimum discharge voltage, purity of electrode materials, purity and properties of the gaseous atmosphere, contamination, and deposits on the electrode surface) were studied.
