Hi Sven,
"The diodes I noticed nothing but I found it very interesting when I turned off the fluorescent lamps in my work room to test how bright the xenon flashes light it did not work anymore.
It strangely only flashes with the light on."
I tried something almost similar with a neon lamp. When shining an UV LED on the neon lamp it turns on at less voltage. This happens because the UV light ionizes the neon thus needing less voltage to ionize to start emitting light. Fluorescent lamps use UV light from mercury to agitate the fluorescent layer. White LEDs use either UV or blue light for the same purpose. This UV radiation could be enough to partly ionize the xenon tube to ignite at less voltage. A Geiger-Müller tube uses the same principle of break down by incoming ionizing radiation.

Ole

Hello Hector, I have tested the coil banger with xenon flash lamp again today. I installed a stronger flash lamp and used a self-wound core that served as an output inductor from a frequency converter as output choke. Diverse diodes tested and switched from 1N4007 to high power and parallel. Capacitor connected from 20 to 60μF. The diodes I noticed nothing but I found it very interesting when I turned off the fluorescent lamps in my work room to test how bright the xenon flashes light it did not work anymore.
It strangely only flashes with the light on. Then I took a 400 watt spotlight and held it in the direction and away again and the switching speed changed.
Whether my workroom in the basement is almost energy-free when lighting is on. I think I live in the Faraday cage. laughing.
1 or 2 times it flashed without voltage, but only with switched on fluorescent lamps.
Very remarkable, whether the xenon tube is excited by the lighting or if additional energy is introduced into the system!?!
