Magnetic Confinement Demonstration!

As part of the Internet Plasma Physics Education eXperience (IPPEX) project, the purpose of this program is to demonstrate the difficulty of trying to contain a plasma inside a tokamak by using magnets. The program produces a black circle which represents a cross-section of the tokamak. Inside this there is a red circle which represents a cross-section of the plasma. Around the tokamak there are eight magnets which can be switched on or off by clicking on them with the mouse. When a magnet is on it will exert a repulsive force on the plasma. the object is to keep the plasma from hitting the wall of the tokamak.

Note From the author:

This program was written by Matthew Fritz, a teacher at Crest Memorial School in Wildwood Crest, with assistance from Daren Stotler of PPPL as part of a summer internship under the auspices of NJ BISEC. The original concept for this program was developed by Jeff Casey, a graduate student at the MIT Plasma Fusion Center. Mike Hanson of Stanford implemented it in C++ for use on Macintosh. This Java version is all new code, but is designed to look and feel like Hanson's Mac version.
