An experimental campaign was recently completed at the U.S. Naval Research Laboratory's Mercury pulsed-power facility, where the feasibility of using a 5 MV inductive voltage adder (IVA) as a pulsed photoneutron source was studied. In these experiments, a large-area bremsstrahlung diode was fielded on the Mercury accelerator, producing an intense, pulsed x-ray beam, which generated photoneutrons when striking an appropriate target. This paper reports on simulations that were performed to study the production of the electron beam in the diode, and the generation and transport of the x-ray beam. Comparison is made between the numerically predicted beam properties and results obtained during the experimental campaign. Various models of electron and ion emission from the electrodes in the generator were simulated, and the effect of model parameter choices on the dose predictions is described.

“…In addition to preventing the MITL electron current from flowing to the diode region, the knob and dustbin can also serve to reduce the amount of debris from the electron beam diode which enters the pulsed power machine [11], [12]. Recently, a Brillouin diode has been proposed which can also prevent debris from reaching the pulsed power generator with the aid of conical MITL [13]- [16]. In this diode structure one conical MITL is employed between the MITL end and the diode.…”

Current transmission efficiency in a conical transition magnetically insulated transmission line (MITL) has been studied experimentally on a 1.0-MV linear transformer driver system, which has 10 identical cavities connected in series with MITL. Transmission efficiencies of anode current as high as 98.4% and 93.1% could be achieved when the MITL operates at load-limited and self-limited flows, respectively. As for the cathode current, because of the sufficient length of conical transition MITL, cathode current is also able to sustain high transmission efficiency. But as long as the diode gap is too large, many of the electrons will be launched into the anodecathode gap and the cathode current near the diode drastically decreases. Particle-in-cell simulations were conducted to validate the conclusions. The simulation results agree with experiments.Index Terms-Current transmission efficiency, magnetically insulation, particle-in-cell (PIC) simulation, pulse power systems.
