Re: Safety

If you want to operate a fusor above 30 Kv, then you probably want to shield more than just the view port with lead. X-rays will start "shining" through the (stainless steel?) chamber walls at these voltages.

Re: Potential safety setup

<t>The diff pump might drag you down to extinction and allow the Van Degraff's to work at or near their potential. If so, then you can have some very penetrating x-rays come of that thing. With no way to meter the current or voltage, you are taking a chance, ...
