Collisions of the second kind in a Penning trap.
Employing a simple analytic model, we demonstrate that electrons oscillating in a Penning trap may drain the energy stored in an active medium. For this process to happen, the electrons must become bunched, and the energy imparted to these electrons allows them to leave the trap resulting in a train of bunches, their angular frequency corresponding to the medium's resonance.
