Re: Ludlum Model 9

If Ludlum had seen that silver paint years ago, they would've trashed that disgusting tan. And that would have been fine by me! GREAT WORK and it looks like a fair price too. I have a similar model 9 that I sometimes use for rock collecting, but it will never look that nice. Thanks for posting all t...

Re: CW Multiplier

I'm attaching my driver circuit that I am currently using for testing my power supply. I have modified the above-mentioned CW multiplier and it can be seen in my recent post in the "images du jour" section of this forum. I will eventually drive this with a commonly available PWM (Pulse Width Modulat...

Re: CW Multiplier

Alex, While you could connect two paralleled MOTs to feed this multiplier, you would be better off to think of something else,in my opinion. First, as this is 8 stages, you would probably not have enough voltage output to easily detect fusion and, since MOTs are iron-core, their maximum frequency is...

Re: CW Multiplier

Alex, I have used the bottom type of multiplier and part of that effort has recently been posted in the images du jour area. If you use that multiplier, you will have to put capacitors across the outer portion of the board where the little l-shaped metal pieces are screwed to the through holes or vi...

Re: My new power supply...

I still don't know about current capability, but right now that transformer would limit me quite a bit. I have found a couple of German made x-ray heads (Heimann) that I will rob the much larger cores from and experimentally determine what their flux saturation is and wind two identical transformers...

My new power supply...

I have started building a new power supply and thought I might share some of the details as I go. This is probably going to be overkill, but I have either scrounged all the parts or bought them cheaply from a popular online auction site. My first images are of my voltage multiplier board bolted to m...

Re: Learning pages - Plasmas

Richard,
I for one would like to see more of these "Learning Pages" where even a busy person can learn from these "bite-size" pages. Keep 'em comin'!!!
