  FEbeam is a compact field emission data processing interface with the
capability to analyze the field emission cathode performance in an rf injector
by extracting the field enhancement factor, local field, and effective emission
area from the Fowler-Nordheim equations. It also has the capability of
processing beam imaging micrographs using its sister software, FEpic. The
current version of FEbeam was designed for the Argonne Cathode Teststand (ACT)
of the Argonne Wakefield Accelerator facility switch yard. With slight
modifications, FEbeam can work for any rf field emission injector. This
software is open-source and can be found at https://github.com/schne525/FEbeam
