A superconducting photocathode with an innovative design will power PolFEL

Scientists from the NCBJ have been developing an innovative superconducting photocathode, that will allow the currently built Polish free-electron laser PolFEL to operate effectively in a continuous wave mode. This will allow distinguishing PolFEL from other such devices in the world. Detailed information was inclosed in the September issue of Vacuum magazine.
