A charge q with velocity v enter into a region with perpendular to magnetic field B, will move in a circular orbit.
The trajectory of the beam will spread out if the bean is deviated with a small angle \theta (dca in the simulation) or with small deviation in velocity (dv)

The angle \theta = 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.

may we change for the point random .. it means become positive ..

The above simulation assume the beam enter into the magnetic field vertically (but there is a small angle deviation).
I think what you mean is that the beam might enter into the field with a angle.
The code has been updated, so that you can change the incident angle with slider c, or drag the red arrow to change it direction directly.
