Simulation codes for light-ion diode modeling

Abstract: The computational tools used in the investigation of light-ion diode physics at Sandia National Laboratories are described. Applied-B ion diodes are used to generate intense beams of ions and focus these beams onto targets as part of Sandia's inertial confinement fusion program. Computer codes are used to simulate the energy storage and pulse forming sections of the accelerator and the power flow and coupling into the diode where the ion beam is generated. Other codes are used to calculate the applied magnetic… Show more

“…[4] Results from earlier 3-D simulations of the Z convolute, [3,5] show that the MITLs can be simulated in 2-D. First, even slightly upstream of the convolute, the boundary and electron flow currents in the MITLs are essentially azimuthally symmetric. Second, until the load stagnates, there are no electrons flowing back into the MITLs from the convolute.…”

“…We have used a lumped circuit model of a LTD cavity to provide the drive pulse for PIC simulations using the Quicksilver code [6]. The PIC simulations use a 2-D axisymmetric model of the coaxial MITL with 1.0 mm resolution across the vacuum insulator and anode to cathode (AK) gap of each of the 21 cavities [7].…”

“…The simulations supporting this work were performed using the finite difference-time domain (FDTD), 3D electromagnetic, PIC code QUICKSILVER [55]. This code utilizes standard FDTD field-solvers and electromagnetic ''particle-pusher'' PIC algorithms [56] to resolve the time-dependent electrodynamics within the disk MITL.…”
