Class AntiprotonAni

java.lang.Object

edu.rit.clu.antimatter.AntiprotonAni

public class AntiprotonAni
extends java.lang.Object

Class AntiprotonAni is a sequential program that calculates the positions of the antiprotons as a function of time and displays an animation on the screen. Each antiproton experiences a net repulsive force from all the other antiprotons. Each antiproton also experiences a force due to a magnetic field perpendicular to the plane in which the antiprotons move.

Usage: java edu.rit.clu.antimatter.AntiprotonAni seed R dt steps N

The program:

1. Initializes a pseudorandom number generator with seed.
2. Generates N antiprotons positioned at random in the square from (0.25R,0.25R) to (0.75R,0.75R).
3. Sets each antiproton's initial velocity to 0.
4. Displays a GUI showing the antiprotons' positions in the square from (0,0) to (R,R). The total momentum of all the antiprotons is also shown.
5. Performs steps time steps and updates the GUI. Each time step is dt.
6. Repeats until the GUI is closed or the program is externally terminated.

The GUI window looks like this:
