Synthetic model of gamma-ray emission during DT experiments on the SPARC tokamak
E. Panontin, R. A. Tinguely, J. L. Ball +10
In thermonuclear plasmas, plasma ions undergoing nuclear reactions emit gamma-rays with energies in the MeV range. Their spectroscopy can convey much plasma information, such as th…
Simulations of internal kink modes and sawtooth crashes for SPARC baseline-like scenarios using the M3D-C1 code
W. H. Wang, C. Clauser, C. Liu +2
A relaxed baseline case, based on the Primary Reference Discharge (PRD) design point, is used to conduct a first dedicated investigation for the most unstable low- MHD instabili…
Interpretive Modeling of plasma evolution during fueling experiments at CMFX
S. Mackie, J. G. van de Lindt, J. L. Ball +7
The Centrifugal Mirror Fusion Experiment (CMFX) is an axisymmetric magnetic mirror with a central cathode which generates an azimuthal, radially sheared, supersonic \( E \times B \…
Effects of 3D printed capsule material on activation thin foil irradiation and counting for fusion neutron yield measurements
D. Lobelo, E. Panontin, X. Wang +3
Activation foils are used to independently measure the time integrated neutron yield and total fusion energy produced in both inertial and magnetic confinement fusion, making them…
Thermal modeling of runaway electron induced damage in the SPARC tokamak
T. Rizzi, K. Paschalidis, S. Ratynskaia +6
The integrity of plasma-facing components (PFCs) in tokamaks is critically challenged by transient events such as runaway electron (RE) impacts. We report the first systematic anal…

The Centrifugal Mirror Fusion Experiment (CMFX) at the University of Maryland, College Park is a rotating mirror device that utilizes a central cathode to generate a radial electri…
Coupled 2-D MHD and runaway electron fluid simulations of SPARC disruptions
R. Datta, C. Clauser, N. Ferraro +3
Runaway electrons (REs) generated during disruption events in tokamaks can carry mega-Ampere level currents, potentially causing damage to plasma-facing components. Understanding R…
Runaway electron generation in disruptions mitigated by deuterium and noble gas injection in SPARC
