Abstract
Non-neutral electron plasmas in a uniform magnetic field are investigated experimentally as a two dimensional fluid. It is confirmed that the phase space volume increases during a vortex merging process, which is consistent with the presence of viscosity. It is also suggested that the following vortex holes movement is associated with a dissipative process.
Keywords
