Re: Function of component in flash tube trigger circuit?



I was always told that the clap of thunder was due to air refilling the
gap
after being punched through by the lightening plasma arc.
That cannot be the reason for the pop when such xenon tubes fire as there
is
no air inside them , why the pop?



"Air" is a mixture of gasses, Xenon tubes are filled with Xenon gas, so no
real difference from that perspective, both the earth and the flash tube
have an atmosphere of gas.

I thought the sound was the shockwave created by the rapidly heated column
of gas expanding, haven't really researched it though.
