ABSTRACT:
A magnetically focused coaxial triode structure includes a central longitudinal cathode, an intermediate control electrode around the cathode, and an outer tubular anode. The control electrode supports the inner cathode and is mounted on insulating spacers at the ends. Axial transverse slots along the control electrode provide openings for the electron beam. The anode has flat longitudinal water cooling channels connected by annular recesses at the ends.
