Unformatted text preview: EE 330 Lab #3 Spring 2007 Alpha Particle Trapped in a Magnetic Field Moving charged particles can be trapped by a magnetic field, i.e., they gyrate around and move along the magnetic field lines. This phenomenon is used in plasma physics to keep plasma confined in a region of space. Also, the radiation belt around the Earth, called Van Allen belt, is a region where charged particles are trapped in the Earths magnetic field. Using MATLAB, visualize the trajectory that an alpha particle follows in a uniform magnetic field. Assume that the energy of the alpha particle is the same as if the particle has traveled through a potential difference of 50 kV before it enters the region of the uniform magnetic field. Also, assume the particle enters that region at an angle of 60 o with respect to the magnetic field lines, as shown in the figure. The magnetic flux density in the region has the same value as the magnetic flux density produced by 1-A current on a straight hollow 20-m long coil with a total of...
