Penning Trap

A penning trap is a type of ion trap that confines charged particles using DC electric fields and a uniform magnetic field (unlike a Paul Trap which uses RF electric fields and no magnetic fields).

One application of Penning traps is for Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR). Image Charge Detection is often used for detection.

ICR example.

SIMION Specific

SIMION examples include

• SIMION Example: icr - basic ICR example.
• SIMION Example: electrostatic_induction - image current measurement
• “malmberg_penning_trap” example (not yet officially added to SIMION) – uses the Poisson Solver in SIMION to characterize the effect of non-neutral plasma space-charge confined in a penning trap
