These diodes utilize a thin annular cathode surrounding a small diameter anode rod extending through and beyond the plane of the cathode. Up to seven rods were simultaneously pulsed with each rod displaying well behaved electrical characteristics (0.8-1.5 MV at impedances of 15 to 30 ohms). Time and spatially resolved X-ray Pin diode detectors demonstrated efficient current (>50%) propagation along each rod. The 50 rads Si that was measured 30 cm from each carbon rod (0.16 cm radius) with Ta cone tips at 1.5 MV corresponds to 10-1000 times the dose of other point radiography sources. While previous rod-pinch experiments were performed with solid rods, a new high-velocity, high-efficiency propagation mode was demonstrated using a hollow cylinder with a 6-/spl mu/m Al wall and a carbon end plug. It is speculated that the propagation was via electron reflexing through the thin anode rod without the need for anode ion production. Also, when no end plug was used, the electron beam appeared to reflex along the entire length of the rod until it lost its energy.","PeriodicalId":410823,"journal":{"name":"12th International Conference on High-Power Particle Beams.

External injection of extra electrons into the cathode cavity provides a reduction of its lowest limiting operating pressure to below 10/sup -4/ Torr. At this pressure the electric strength of the acceleration gap is sufficient to extract an ion beam of energy several tens of KeV, and the scattering and resonance charge exchange of accelerated ions at residual gas atoms affect the parameters of the beam in this transportation toward a target only slightly.
