Direct Microstability Optimization of Stellarator Devices
R. Jorge, W. Dorland, P. Kim +4
Turbulent transport is regarded as one of the key issues in magnetic confinement nuclear fusion, both for tokamaks in stellarators. In this work, we show that a significant decreas…
Analysis and mitigation of pulse-pile-up tail artifacts in warm-plasma pulse-height X-ray spectra
Taosif Ahsan, Charles Swanson, Christopher Galea +4
Pulse pile-up in pulse-height energy analyzers increases when the incident rate of pulses increases relative to the inverse of the dead time per pulse of the detection system. Chan…
GX: a GPU-native gyrokinetic turbulence code for tokamak and stellarator design
N. R. Mandell, W. Dorland, I. Abel +4
GX is a code for solving the nonlinear gyrokinetic system for low-frequency turbulence in magnetized plasmas, particularly tokamaks and stellarators. In GX, our primary motivation…
Permanent magnet optimization for stellarators as sparse regression
Alan A. Kaptanoglu, Tony Qian, Florian Wechsung +1
A common scientific inverse problem is the placement of magnets that produce a desired magnetic field inside a prescribed volume. This is a key component of stellarator design, and…
Design of an arrangement of cubic magnets for a quasi-axisymmetric stellarator experiment
K. C. Hammond, C. Zhu, K. Corrigan +5
The usage of permanent magnets to shape the confining magnetic field of a stellarator has the potential to reduce or eliminate the need for non-planar coils. As a proof-of-concept…
