We propose to couple a trapped single electron to superconducting structures located at a variable distance from the electron. The electron is captured in a cryogenic Penning trap using electric fields and a static magnetic field in the tesla range. Measurements on the electron will allow investigating the properties of the superconductor such as vortex structure, damping and decoherence.

We describe a versatile planar Penning trap structure, which allows to dynamically modify the trapping configuration almost arbitrarily. The trap consists of 37 hexagonal electrodes, each of 300 mikron diameter, fabricated in a gold-on-sapphire lithographic technique. Every hexagon can be addressed individually, thus shaping the electric potential. The fabrication of such a device with clean room methods is demonstrated.
