MEDeGUN is an electron gun to be used in an Electron Beam Ion Source designed to serve as C6+ source for LINAC-based hadron therapy facilities. The latter require short pulses of particles at a high repetition rate, which exceeds the possibilities of present-day ion sources. In spring 2017, the MEDeGUN assembly was installed at the TwinEBIS test bench at CERN and an electron beam of more than 1A at 10 keV electron energy through the two Tesla solenoid has since been propagated with very low losses which is a major step forward.
