Summary[edit]

Description
English: This photo shows a 30 joule flash discharged in 3.5 microseconds, using external triggering. The system is at 1/3 power, (maximum safe operating energy is 90 joules), and the camera is behind a shade 10 welding filter. With such a short duration, electrical wattage is 8.5 million. With external triggering at such high speeds, the arc does not have time to move away from the glass before the full amp load passes through. The arc does not have time to fully heat the xenon and fill the entire tube[1], and maintains following the trigger wire closely. This tube showed serious signs of wall ablation after just a single shot.

The current density was much higher than hoped for, and produced a bluish flash, and the arc looked very green to the human eye through a welding lens. It appears purple in the photo because the camera does a much better job of imaging the large amounts of near-infrared light than the eye.[2][3]

The arc length is 150mm, and bore diameter is 10mm.
