The Memory Scaling of Reverse-Mode Differentiation in Particle Accelerator Simulations with Space Charge
Arjun Dhamrait, Edoardo Zoni, Axel Huebl +7
The recent development of differentiable simulation codes for particle accelerators has enabled gradient-based workflows that promise finer control and more realistic modeling of a…
Achromatic optics using nonlinear plasma lenses for beam-quality preservation between plasma-accelerator stages
C. A. Lindstrøm, E. Adli, J. B. B. Chen +6
Plasma acceleration promises to deliver high-energy particle beams by combining, or staging, several low- or medium-energy accelerator stages. However, chromatic aberrations from t…
AMReX and pyAMReX: Looking Beyond ECP
Andrew Myers, Weiqun Zhang, Ann Almgren +4
AMReX is a software framework for the development of block-structured mesh applications with adaptive mesh refinement (AMR). AMReX was initially developed and supported by the AMRe…
Energy-Preserving Coupling of Explicit Particle-In-Cell with Monte Carlo Collisions
Jean-Luc Vay, Justin Ray Angus, Olga Shapoval +3
The Particle-In-Cell (PIC) and Monte Carlo Collisions (MCC) methods are workhorses of many numerical simulations of physical systems. Recently, it was pointed out that, while the t…
A High-Quality Workflow for Multi-Resolution Scientific Data Reduction and Visualization
Daoce Wang, Pascal Grosset, Jesus Pulido +8
Multi-resolution methods such as Adaptive Mesh Refinement (AMR) can enhance storage efficiency for HPC applications generating vast volumes of data. However, their applicability is…
