End-point energy measurements of field emission current in a continuous-wave normal-conducting rf injector

End-point energy measurements of field emission current in a continuous-wave normal-conducting rf injector

The LANL/AES normal-conducting radio-frequency injector has been tested at cw cathode gradients up to 10  MV/m. Field-emission electrons from a roughened copper cathode are accelerated to beam energy as high as 2.5 MeV and impinge on a stainless steel target. The energies of the resulting bremsstrah...
