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
