T>While not a tesla generator question ... No argument there. Still, a Tesla coil can be used to power the Dees... T>I want to build a 20,000+ gauss U shaped magnet for use on a small T>cyclotron. I am trying to determine what grade of steel I should use T>that could be purchased from a commerical steel supplier. I am going to Don't!! Do not use steel under any circumstances. This calls for soft iron! The softest soft iron money can buy. Then best to anneal it yourself any way. - - - - - - Your problem is not going to be the iron. It's going to be the copper. For the windings. Eons ago plans for building very powerful magnets were published in the "Amateur Scientist" column in "Scientific American". These were reprised in the 3-volume "Amateur Scientist" books. They described a primary comprised of short, curved copper sheets (like a segment from a donut) that were interleaved over one another to form a continuous con- ductor around the iron core. - - - - - - This is a very difficult and expensive undertaking of which the magnet is the least. Building a cyclotron is one thing. Getting it to resonate (let alone maintain resonance) is =quite= another. Which is why no one builds cyclotrons anymore (i.e. for particle and nuclear research) - it was a cute trick in its day which served to get O. E. Lawrence some recognition (and much needed funding) but that's about the use of them. Be prepared to spend a lot of lonely and frustrating nights, (and to get a second mortgage on the house). Cycled around on that one, Robert Michaels
