🧲 Penning Trap Ion Cloud (2D top and side views)

2D top and side views of a Penning trap: a magnetic field plus a quadrupole electric field confines an ion cloud. Follow one tracer ion through its cyclotron, magnetron and axial motions and see when the trap becomes unstable. Same Boris integrator and frequency formulas as the 3D page, with four numerical checks.
