Re: Cyclotron seeds

An interesting and entertaining experiment to read about. I don't think I would have forseen that problem with the JB Weld either. How big's the next one slated to be?

Re: Circularly polarised RF field confinement.

Hi Chris,
Is there anywhere that has more information on this? Specifically what the numbers are referring to.

Re: Electrostatics question.

<t>I have had the same question as Chris. Unfortunately I am only more confused by Dave's explanation. Maybe I can make more sense of it later.<br/> <br/> I would like to consider the concept without thinking of any other objects or charges around, just a single sphere.<br/> <br/> Consider measuring...

Re: Alternating Current Demo Fusor

<t>I agree with Richard. Not only are the grid wires a much tighter radius, but the inside of the shell is convex too, and any excess charge will reside on the outside of the shell, not the inside. There would be a much greater electric field on the wire causing much more emission.<br/> Not to get o...

Re: A compact DIY cyclotron package solution.

<t>If one was willing to be locked into a permanent configuration, maybe it could first be assembled as you have, then, by sliding them around some, add a thin layer of epoxy between the magnets and one of the plates. After the epoxy cures, then perhaps the other plate could be slid on and off (?)<b...

Re: A compact DIY cyclotron package solution.

Chris,

It seems to me that without the studs it might be possible to leave the magnets in place on one plate and slide the other plate on and off for access as needed. From your experience does that seem possible?

Re: A compact DIY cyclotron package solution.

<t>Thanks for the report Chris. Very interesting.<br/> <br/> You probably know this already, but it's my understanding that there's nothing to be gained from stacking the neodymium magnets - in other words putting them in series doesn't add to the total flux in the magnetic circuit.<br/> <br/> I wou...

Uranium: War, Energy and the Rock That Shaped the World by Tom Zoellner

This is a new book out covering the history of uranium. I don't have any immediate plans to read it, but I thought some here might be interested.
