Thanks for the offer of the tubes but these will, I suspect, be xenon tubes. Xenon has an afterglow. My intent is to photograph bullets in flight. The best I can do with a xenon flash is shown on my website under "high-speed". I'm hoping to build a truly high-speed flash with a duration of 0.5 microseconds. The fastest xenon is 1/100,000th of a second. Edgerton noted this in his book "Electronic Flash, Strobe".
