A charge q with velocity v enter into a region with perpendular to magnetic field B, will move in a circular orbit. /htdocs/ntnujava/ejsuser/2/users/ntnu/fkh/chargeinBvdc_pkg/chargeinBvdc.propertiesFull screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
The trajectory of the beam will spread out if the bean is deviated with a small angle (dca in the simulation) or with small deviation in velocity (dv)
The angle = dca * (random() -0.5); // where random() give random number between 0-1
The velocity v=V+ dv* (random() -0.5);
The trjjectory for all different possible paths are shown in the following simulation.
