The magnetic field is relatively weak. The particles stay more or less confined. The maximum vertical speed of the D+ ions is about 2,2 E6 m/s (I checked this in the simulation). This is about the speed necessary for fusion.
Because in the simulation there are so few particles, no colisions take place. In reality there would be collisions and some particles also will obtain high speeds in the lateral direction. To stop them from escaping the magnetic field should be stronger.
