Magnetic reconnection is a process, in which magnetic field lines break up at the magnetic X-point and rearrange, often accompanied by a transfer of magnetic field energy into thermal energy. The plasma response to magnetic reconnection is characterized by the formation of a current sheet in an area around the magnetic X-point, where the magnetic field lines diffuse. The shape of the current sheet has a strong influence on the evolution of reconnection. In the linear VINETA-II experiment the plasma current is provided by an array of plasma guns, which act as an electron source and influence the spatial distribution and amplitude of the reconnection current. The plasma guns can be operated individually which gives the possibility for a variety of initial conditions for the current sheet. In this contribution the spatiotemporal evolution of the reconnection current sheet is studied in dependence of the current source and reconnection drive scheme. Special attention is paid to the response of the current sheet to a spatially inhomogeneous reconnection drive scheme.
