Re: Ion Gun Construction / Proposition

<t>Hi Phil:<br/> A diagram of the inside of a duoplasmatron is detailed in the following book.<br/> <br/> "Building Scientific Apparatus", Moore, Davis and Coplan, 1989. A modern version of Strong's 1938 book on steroids. Into its eleventh printing!! Really superb. How to make ion guns!!!, etc. Comp...

Re: Ion Gun Construction / Proposition

<t>I was going the daisy chain them in a large supply<br/> but many caps,spark gaps and coils. My original idea was to modify the duoplasmatron structure with a inductively heated neon sign electrode dipped in strontium , calcium carbonate and barium carbonate fired to leave strontium barium oxide a...

Re: Ion Gun Construction / Proposition

<r>I've been thinking about filamentless ion guns using an induction heater to make a anode glow.<br/> Use a coated form and heat it to 1500 degrees....<br/> red heat using electrical induction. <br/> If you want to see one in a action goto:<br/> <URL url="http://www.powerlabs.org/index.html">http:/...

Re: Magnetic flux compression generator for a pulsed fusor?

<t>Homopolars are a pretty big field but here's some links that might shed some light.<br/> <br/> search under homopolar but use the university sites first. UT Austin, Mich,MIT ect.<br/> They have clear explanations of the homopolar generator.<br/> Warning *****most sites are not math friendly*****<...

Re: Fusor stable run times?

<r>The group is still sorting that out as we speak.<br/> Richard Hull has had the longest run on his fusor 3 to date. His run on the video tape was in the twenty to thirty minute range. Yes Virginia the containment is not measured in microseconds in the continious fusor.<br/> I'm only pulsing to get...

Re: Pulsed Fusor Metrology

<t>I have found a way to record sound at the pulse site.<br/> mummify your tape recorder with it turned on.<br/> The mike is totally covered but has pin pick holes<br/> for sound.<br/> To make videos with digital cameras is about the same. I use a metal box (Alltronics or Newark) with a Window coate...

Hv parts

<t>A good source of hv parts are defunct radio stations.<br/> I just bought some terrific parts for pulsed and steady state work. For twenty bucks on Ebay I got the guts from a fairly new radio transmitter. The four hv diode assemblies were worth more than twenty a piece.<br/> 12kv @ 30 amps. What a...

Re: All-In-One Detector Board

Hi Richard:

If you need assistance on the scut work of lists
and bill of materials,I would be happy to help.
I'm beginning to get the swing of this retirement bit.
I have all the office tools and it wouldn't be a distraction.
