Build Your Own Cyclotron

mindpixel writes "Physics Today is running a story about Tim Koeth's 12 inch cyclotron. Here's a quote that says it all: 'I was sitting in Tom Devlin's modern physics lecture. He described the principle of the cyclotron. He said it required a lot of RF power. I was--and am--a ham radio operator, so RF was no problem. It needed a big magnet; I knew I could find one of those. How tough could a vacuum system and chamber be?'"

    Meloy implants the electrodes from this device into the back of the patient, at the bottom part of the spinal cord. When the electrodes are stimulated with a remote control, the brain interprets the signal as an orgasm, he said. The device is about the size of a pacemaker and can be turned on and off with a handheld remote control.

    Another thing you should know if you take physics at Rutgers is that the physics auditorium is probably exposing you to mercury vapor.

    Centuries ago I was doing a thesis project at an Air Force lab, and was measuring some pressures with a mercury manometer about six feet high, made of 1/4 inch ID tubing. If I had ever blown that thing, there would have been a couple of pounds of mercury skittering around on the concrete.

    Then a safety inspector came in and told me I had to put an overflow bottle on the manometer. So I did -- I taped a 2-ounce bottle to the top, connected it with a piece of Tygon, and the guy was happy.

    when my dad was in highschool he and his brother snuck into the chem lab and ended up dumping a jar of Hg all over the floor.

    Frank Zappa's father worked as a meteorologist at a military arsenal and used to come home with mercury for the kids. His autobiography talks about it: "One of the things I used to like to do was pour the mercury on the floor and hit it with a hammer, so it squirted all over the place. I lived in mercury."

    My father never brought home so much as a blob. I might have been a rock star by now. Gee, thanks Dad.
