Tubes?

[EMdevices]

So "longitudinal" waves or "scalar" waves have no magnetic components?Ã,  Hmm,Ã,  that's too bad, I was realy hoping

This should probably be discussed in some other thread, but anyway, no magnetic component has something to do with "curl-free vector potential".

But I think you already know that EM.

This is in reference to your comment on shielding. There are 2 primary resonances in a simple coil, the primary transverse resonance, and the primary longitudinal resonance. A faraday cage will shield energy at the primary transverse resonance, while the primary longitudinal resonance energy will pass right through that faraday cage as if it were not even there. That longitudinal resonance will be picked up by an identical coil on the outside of the faraday cage.

Thanks for looking  in Bob.

It is my "guess" that the longitudinal resonance is what we want to use . but it is, in this case a "ring" of itself? ....Kind of a contradiction. It sure does my head in at times. Sometimes i think that I am learning.
Would it be so that in the centre of a big ring it would be less?

Do you have any insight to offer  us as to the difference between ss and tubes regarding the reason that Steven has said to use them because it is easier?

Hi all,

I quote myself, what a shame!

However, I was asking myself if the former kind request hereby quoted simply remained unnoticed or it was dismissed?
No interest from your side, no enough expertise or is there any other reason (I can?t figure it out) for the lack of any reaction?

You know, I can really use some help here?
More or less of a help given, it would be still something!
(Several tubes will arrive tomorrow, in a bulk delivery.)

Many thanks,
Tinu

Hi good fellows,

I?m writing here in a kind request I address to you, to all experimenters with tubes.
Please check the following thread if you haven?t done yet: http://www.overunity.com/index.php/topic,3086.0/topicseen.html. It?s about Universons.

I do not intend to bother you too much but tubes can be used for confirming the universons flux. While I?m waiting for my tube source, I?ve thought some of you may be interested in the above topics. All it takes it would be pulsing the tube and check for various effects along the path of the accelerated electrons. Those effects should include induced EMF in a regular metal (wire), which in principle can be detected with an oscilloscope even if the magnitude would be too small for other practical purposes.
The energy levels involved in Mr. Poher?s experiments are on the order of 15J per pulse. This is quite big for a regular tube, although for single pulses a tube can be overdriven. I?ll probably burn some low power tubes in the process but at present I don?t have any. This is going to change during the next week. Meanwhile, your interest and your input on the above would be greatly appreciated.

I have another question. If there is a tube wizard among us, please let me know the kind (types) of tubes which have the following characteristics:
- longitudinal configuration (i.e. electron flux is not radial from the central filament to the cylindrical grids&anod), if any.
- high power tubes (diodes, in principal but also other types should work assuming that the other grids are kept at fixed potential) that are commercially available.
I will work in the first phase with Russian military tubes used for microwave equipments but that will make my life miserable as I?ll probably not be able to find their functional characteristics.
Therefore, my question aims toward later purchasing some well documented tubes, especially if the first experiments (more or less blindly conducted) will prove themselves positive.

Please reply in the above thread.
Many tx,
Tinu

Tinu,
thanks, well worth some "exploration".

I had not previously seen that . Not sure why.too much soap??

I use 12au7 for overdrive experiments because i have lots of them to burn.

I have not destroyed any yet but I will do so if it is possible

they are similar to the 6bq7 that has been suggested.

Your other questions about the physical structure are interesting but are beyond my experience and knowledge but i hope that somebody can contribute.
