Seeding of Self-Modulation using Truncated Seed Bunches as a Path to High Gradient Acceleration
N. Z. van Gils, E. Belli, M. Bergamaschi +11
This manuscript proposes a method to enable controlled high-gradient particle acceleration when requiring self-modulation of the drive bunch. While electron bunch seeding of self-m…
Non-dimensional confinement scaling in similar negative triangularity plasmas on the DIII-D and TCV tokamaks
A. Marinoni, C. Chrystal, S. Coda +25
Similarity experiments were performed on the DIII-D and TCV tokamaks to explore the scaling of energy confinement in negative triangularity plasmas using non-dimensional variables.…
Minimizing CGYRO HPC Communication Costs in Ensembles with XGYRO by Sharing the Collisional Constant Tensor Structure
Igor Sfiligoi, Emily A. Belli, Jeff Candy
First-principles fusion plasma simulations are both compute and memory intensive, and CGYRO is no exception. The use of many HPC nodes to fit the problem in the available memory th…
Evaluation of Intel Max GPUs for CGYRO-based fusion simulations
Igor Sfiligoi, Jeff Candy, Emily A. Belli
Intel Max GPUs are a new option available to CGYRO fusion simulation users. This paper outlines the changes that were needed to successfully run CGYRO on Intel Max 1550 GPUs on TAC…
