Re: My first XRT and some questions

My mistake. I didn't see the laminations on the core. That small of a laminated core would be a very small duty cycle. My old eyes on a small phone display fooled me.

Re: The piggy is mobile!

Once again, I'm impressed! I can't wait to see what this magnificent lightning generator will do!

Images of Tesla sitting in front of one of his giant coils with beautiful arcs all around comes to my mind, except this is DC with a LOT of stored energy!!! :)

NICE WORK!!!

Re: My first XRT and some questions

If the core is 9kg and the transformer is rated at over 1200 watts (85kV x 15mA), I would venture to say it is NOT meant to be run off 50-60Hz line frequency. I would be willing to bet that the core is ferrite and that this transformer operates off tens to hundreds of kHz. I would most likely connec...

Re: The piggy is mobile!

I'm impatiently waiting...I love power electronics, but I am just standing back watching in awe and jealousy to see what kind of beast you are going to feed with this! Just kidding, I can't wait to see what kind of power supply you are contemplating. Based on your other work I'm sure I won't be let ...

Re: Radiation shielded camera, 10000rem/sec 1-4MeV x-rays

That's a really cool post! In the fission business, we often run an underwater camera in the vicinity of irradiated fuel assemblies and they always have a few pixels become unresponsive and you can always see flashes of light when in a radiation field of any strength. An interesting thing that I fou...

Re: The piggy is mobile!

I'm assuming those caps are going to be used as voltage multiplier. How big are they? What are you going to use for rectifiers? That will be an awful lot of stored energy...

I can't wait to see what application you have in mind :)

Re: The piggy is mobile!

Wow! That will surely be able to supply a ton of current. What power hungry beast are you going to feed with that?

Re: NIM Bin and other rack pics

Nice pictures/great work! What model of power supply and bin is that? I posted an instruction manual some time back in the "Files" section that covers the TB-3 (Tennebin-3) NIM Bin and the TC909, 910, 911, and 930A Power Supplies. This manual includes schematics and adjustment procedures for the pow...

Re: high voltage power supply

That power supply, while being the correct polarity and sufficient voltage, can only put out 0.33mA. While this will be enough voltage for fusion to occur, the number of fusions is dependent on current and you would be hard pressed to be able to measure the feeble amount of fusion from it.
