Antimatter in a Penning Trap

This demonstrates the plasma simulation by holding a whiff of antimatter in a Penning trap. A Penning trap is a configuration of magnetic and electric fields (magnetic solenoid and electric quadrupole) that contain a cloud of charged particles without letting them touch the walls. Antimatter is often stored this way for experiments.


You can rotate the camera left and right with the mouse. See how the antimatter flattens and rotates like a little galaxy?


The documentation walks you through the process of building each of the tutorials and includes assets (graphics and GameObjects) for all of the demos.
