Test of a high efficiency relativistic magnetron with diffraction output (MDO) and spherical cathode endcap

Summary form only given. A previous computational study of a relativistic magnetron with diffractive output at UNM using MAGIC [1] indicated an electronic efficiency of 70% [2]. The original anode design in this study was tested in experiment. Some subtle changes in the source design were necessary, such as introduction of a Helmholtz-like magnetic coil… (More)
