Abstract
Hotspots can be generated in superconducting tunnel junctions through dissipation of Joule energy. They can be imaged by scanning the junction surface with the electron beam of an electron scanning microscope equipped with a low temperature stage. It is shown that caused by inhomogeneities of the tunneling barrier the local current density can become very high leading to hotspots at these parts of the junction at relatively low total tunneling current.
