Particle Trap & Field Visualizer
Drop a preset to load a Paul trap, Penning trap, or quadrupole guide. Tap Add element to drop electrodes, coils, and charged particles freely.
Camera — left-drag to orbit, right-drag to pan, scroll to zoom.
Select an element in the scene, then tune position, charge, voltage, and oscillation frequency in the Inspector. Watch the field lines re-form in real time.
Field lines trace the live electric field. Equipotentials render iso-voltage shells. Trails show particle history — useful for spotting micromotion in RF traps.
Tip — Paul traps need an oscillating quadrupole. The frequency must satisfy the Mathieu stability criterion to confine ions; tune the frequency slider until the cloud stops blowing apart.
