Re: Reuter Stokes Proportional Counter

<t>I had pretty good luck getting B-10 tubes to work in the past.<br/> <br/> Like Richard said, you need to have voltage control in addition to discrimination level control. At a certain voltage, the gamma level was vastly below that of neutrons. 50V lower, there was nothing and 50V higher the gamma...

Re: Fusor Voltages are Dangerous

<t>>100KV of direct whole body or entire upper torso x-rays for long continuous periods would surely do it, but working on a fusor? No, I'm sorry.<br/> <br/> <br/> Such things have happened to member(s) of this forum with reported closely correlated illness. I was not involved in such activities.</t>

Re: Fusor Voltages are Dangerous

<t>Adding to the HV being one pole of a capacitor, the worst case here is if the other pole is an actual capacitor. This is the only time I've been shocked by my fusor. I did a long run while leaving a high voltage capacitor attached to an exposed wire but not actually connected to anything (and ear...

Re: Opinions on WiederLabs 100kV Feedthrough

Yes, that is true... but the point is it's a waste of money to get a 100kV 3A feedthrough if all you're ever going to run is 30kV 10mA... $1175 is quite possibly more than anyone on this site has ever paid for a feedthrough.

Re: Opinions on WiederLabs 100kV Feedthrough

<t>First off, unless you're making a fusor to crush every fusor record times a hundred, that is a very overkill feedthrough.<br/> <br/> I'm guessing Wieder labs doesn't actually make it themselves since as far as I know, they are largely a small company formed from a DIY environment. This would make...

Re: The Neutristor

I saw that many months ago, based on technical descriptions it sounds like it's just a very, very small fusor.

Re: 15 kW variac

Well, first off you don't get a 15kW variac, since you're not actually going to put 15kW into your fusor. Get whatever variac you want.

You'll need to build or find an inverter capable of generating the 30khz. There is quite a bit of info on this in the forum's history.

Re: 15 kW variac

Are you sure it's not 30kHz? Sure doesn't look like a 15kW mains transformer, and 30hz makes no sense anyways.

Assuming it's 30kHz, you will need an inverter not just a variac.

Search. In fact, there is an entire sub-forum dedicated to your question. You posted in it, so scroll down a bit.

Re: Does this look like a good supply?

<t>It would work (and is how it's usually done) if you were driving it from a high frequency transformer, but at 60hz from a MOT/NST/OBIT/etc. to get fusion currents you would need huge capacitors in the multiplier. This has been done with series strings of Microwave Oven caps by members of this for...
