Compact experimental negative triangularity reactor (CENTAUR): A design study for a compact, affordable breakeven tokamak

S. Freiberger, Evan M. Bursch, Javier Eduardo Chiriboga, Hiro Joseph Farre-Kaga et autres

Abstract This work presents the compact experimental negative triangularity reactor (CENTAUR), a low overnight cost, high-field tokamak, breakeven reactor design, achieving a predicted total fusion power of 40 MW and scientific energy gain of 1.3. Ballooning stability calculations confirm that the device's …

Access and limits of RMP ELM suppression with n = 1 fields in DIII-D

P. Lunia, N. Leuthold, N.C. Logan, C. Paz-Soldan et autres

Abstract This work reports on DIII-D experiments aimed at extending resonant magnetic perturbation (RMP) suppression of edge localized modes (ELMs) to n = 1 fields, where n is the toroidal mode number. Modeling of the 3D ideal MHD plasma response to the …

TokaMaker: An open-source time-dependent Grad-Shafranov tool for the design and modeling of axisymmetric fusion devices

C. Hansen, I. G. Stewart, D. Burgess, M. Pharr et autres

In this paper, we present a new static and time-dependent MagnetoHydroDynamic (MHD) equilibrium code, TokaMaker, for axisymmetric configurations of magnetized plasmas, based on the well-known Grad-Shafranov equation. This code utilizes finite element methods on an unstructured triangular grid to enable capturing accurate …

The Eel Pulsar Wind Nebula: A PeVatron-candidate Origin for HAWC J1826−128 and HESS J1826−130

D. Burgess, Kaya Mori, Joseph Gelfand, Charles J. Hailey et autres

Abstract HAWC J1826−128 is one of the brightest Galactic TeV γ-ray sources detected by the High Altitude Water Cherenkov (HAWC) observatory, with photon energies extending up to nearly ∼100 TeV. This HAWC source spatially coincides with the H.E.S.S. TeV source HESS J1826−130 …

NuSTAR broad-band X-ray observational campaign of energetic pulsar wind nebulae in synergy with VERITAS, HAWC and Fermi gamma-ray telescopes

Kaya Mori, Hongjun An, D. Burgess, M. Capasso et autres

We report recent progress on the on-going NuSTAR observational campaign of 8 TeV-detected pulsar wind nebulae (PWNe). This campaign constitutes a major part of our NuSTAR study of some of the most energetic TeV sources in our Galaxy detected by VERITAS and …

Parsek2D: An Implicit Parallel Particle-in-Cell Code

Stefano Markidis, Enrico Camporeale, D. Burgess, Rizwan-uddin Rizwan-uddin et autres

A Particle-in-Cell (PIC) code, called Parsek2D, for the simulation of astrophysical and space plasmas is presented. Parsek2D enables simulations with large grid spacing and long time step, by means of implicit time differentiation and parallel computing. An implicit formulation of the PIC …

Renumbering unstructured grids to improve the performance of codes on hierarchical memory machines

D. Burgess, Michael B. Giles

The performance of unstructured grid codes on workstations and distributed memory parallel computers is substantially affected by the efficiency of the memory hierarchy. This efficiency essentially depends on the order of computation and numbering of the grid. Most grid generators do not …

A Parallel Framework for Unstructured Grid Solvers

D. Burgess, P. I. Crumpton, Michael B. Giles

The aim of this work is to solve large two and three dimensional CFD problems using unstructured meshes. These problems are too large and too slow to put on sequential machines so parallel machines are required. Writing one off, machine specific parallel …
