Addition of a One-Meter Extension and Right-Angle Bend in Vacuum to a Compact, 1-MV, 6-kA Radiography Source

Summary form only given. Hybrid radiation source (HRS) is a compact pulsed power generator consisting of a commercial flash X-ray system that has been retrofitted with a custom front-end assembly, replacing a sealed glass tube. A new high impedance (~120 Ohm) space-charge-limited (SCL) diode was fielded on the HRS. This diode produces a ~1.6 mm diameter X-ray spot suitable for high-resolution radiography. This system has been modified by extending the diode from the generator with a one-meter-long vacuum transmission line. Also, the anode has been rotated to point perpendicular to the transmission-line axis. The extension and rotation allow for the placement of the high-yield, small-spot-size, HRS radiographic source in previously unreachable locations. Parameters such as voltage, current, and source size have been measured and analyzed, allowing for optimization of the radiographic source. Discussion will also include circuit diagrams, simulation models, and diagnostic traces.
