Subject: [TSSP] Ion Cloud Loading
Hello all,
For a long time now, many have suggested that an ion cloud
hanging around the secondary terminal necessitates detuning the
primary downward somewhat to compensate. I have long doubted this
mantra (without proof) but have devised a relatively simple test that
could be performed to establish where the truth lies. My doubt arises
as I think that any detuning of the secondary can be explained (I
think) by capacitance (and resistance) added visible streamer length
alone.
The test does not involve spark production (important).
Instead, one uses the usual setup of a signal generator and aerial
probe to monitor the secondary ringing alone, and then introduce an
ion cloud around the terminal using some other devices (like ozone
generators. UV generators etc. Any significant shift in secondary
frequency should be quite observable.
I think this is an appropriate forum to check this out and add
to the knowledge base. Is anyone equipped to easily do this test?
Regards,
Malcolm
