We study the time evolution of a charged particle in a Penning trap in the framework of open quantum systems. The interaction with the environment istaken into account by imposing Lindblad operators which are linear in the canonical variables. For the special case of a proton in an asymmetricPenning trap we compare the dynamics with earlier results obtained from the unitary time-dependent Schrödinger equation. A possibility to estimatethe spatial decoherence time of the system is discussed, and approximate decoherence time scales are given for different ions.
