The study of the dynamic response materials induced by electron beams requires precise knowledge beam when it interacts with material. In this framework, CESAR generator is used at CESTA. drives a field emission diode that delivers single-shot intense pulse (≈1 MV, 300 kA, and 100 ns). propagates into gas-filled chamber where focused magnetic onto an aluminum target. analysis characteristics target position allows us to estimate initial conditions required for hydrodynamic simulations....
Validation of plasma physics codes like EMPIRE requires performing uncertainty quantification comparing experimental data and simulation results. The Short Pulse, High Intensity Nanosecond X-radiator (SPHINX) is a high-voltage, high-shot rate bremsstrahlung accelerator at Sandia National Laboratories. SPHINX can additionally be operated in electron-beam mode by changing from the standard tantalum converter to 1-mil titanium connected drift cell that filled with low-pressure gas. primary beam...
Verification and benchmark problems allow code developers to assess numerical accuracy increase confidence that specific sets of model physics were implemented correctly in the for application real world problems. In this work, we compare a test relativistic (500keV) electron beam propagating through pressurized (0.1 mbar) Ar gas cell present results between general plasma EMPIRE hybrid GAZEL. can be run as fully kinetic Particle-In-Cell (PIC) problem with Direct Simulation Monte Carlo...
ability of each code to perform contaminant transport. The purpose the investigation was establish a basis for, and validate follow-on work that conducted in which 1-D GoldSim model developed by abstracting information from Porflow 2-D 3-D unsaturated saturated zone models then benchmarked produce equivalent transport results. A handful contaminants were selected for code-to-code comparison simulations, including non-sorbing tracer several long- short-lived radionuclides exhibiting both...
