Build a Moray-like device

[Ros-Co.]

Dear Mr Perrault!

I'm a relatively new member in the forum, but i have some experience in hig voltage techniques, like Tesla-coils, flyback transformers, etc.
If possible, i need some help to build a moray-type device.

I have bulit a dirt'n cheap ion valve, using like a rectifier, and i placed i to my "mini"  tesla coil. It is semiconductor-based, and planned by Skori
http://skory.gylcomp.hu/tesla/mini_tesla.html


it's about 500W to 1KW peak power from 12V, with very shape pulses. My coil's Resonance about 384 KHz. 

An ion-valve made from a copper wire, and from a copper stripe, bended to round form.  My friend said to me, it was too bumpy surface, do rectifying.  I'm going to plan to replace it to a stainless steel pipe with very shine surface.

here are the videos:

The outer ring of the valve connected to an antenna, about 20 metres long.  The antenna was slighly charged statically.  (So the rectifier was works) (2nd video) I detected it with a little neon bulb.  The interesting part, that I can discharge it more than 3 times. But i didn't observe some OU effect.
How can I increase the OU effect?

I think:
-resonance frequency can be placed the main universe frequ (I heard about 1,9MHz)
-more power?
-radioactive material (ep. thorium dust placed to a surface of a tube)
-antenna matching elements (variable inductor?)

And my last question, is the electret effect.  I read about a method conditioning a coax cable.  It,s clear, but I don't understand, that the outer
foil, (or wire moggan) should be removed?   About how times is it increase the OU effect?



At the end, If anybody interested in my experiments

Thank you for your help!

Hi,

you set up an interesting page, but let me give you one advise:

-radioactive material (ep. thorium dust placed to a surface of a tube)

Hands off radioactive powders like ThO₂, UO₂ or any other radioactive material. They are highly toxic. If you accidently inhale some of this dust, these small particles get stuck in your lungs and keep radiating there for ever. The result is you will definitely get lung cancer sooner or later. These materials must only be handled in glove boxes !

Ok, thank you for your advise.  I know, it's not a toy. 
Are there any non-toxic, but avaiable radioactive material?  But I think radiating is harmful anyway.

Hello Ros-Co.,

Does your antenna charge back up without any artificial source attached to it?

Actually... why not leave the outer foil? Apply positive voltage to the center wire and  negative to the outer foil.  you then have one big electret. Try it reversing the conditioning polarity too and see what difference this makes. Next measure the resonant frequency of the cable that you put up between two insulators. Then, build a a tank circuit that is tuned to this frequency. Lastely rectify the oscillations with a diode bridge.

Hi!

My antenna doesn't charge without any artifical source.  I can't capture any ambient electric energy.
Is it necessary for work?

I heard about that the device works indoor too, because the antenna captures radiant energy. (If you pumped it with special impulses, and special frequency)  Is it correct?   Moray's second generation device is not use antenna.


I'll try the electret trick.  I read your idea with oil heating of the cable.  My flyback driver easily charge the cable up to 25KV.
