TL;DR: The National Spherical Torus Experiment (NSTX) is currently being upgraded to operate at twice the toroidal field and plasma current (up to 1 T and 2 MA), with a second, more tangentially aimed neutral beam (NB) for current and rotation control, allowing for pulse lengths up to 5 s as mentioned in this paper.

Central safety factor and β N control on NSTX-U via beam power and plasma boundary shape modification, using TRANSP for closed loop simulations
TL;DR: A novel approach to simultaneously controlling βN and the value of the safety factor on the magnetic axis, q0, through manipulation of the plasma boundary shape and total beam power, is proposed.
Light curve completion and forecasting using fast and scalable Gaussian processes (MuyGPs)
TL;DR: This paper presents a novel approach to predicting missing and future data points of light curves using Gaussian Processes (GPs), and shows that the method outperforms feedforward DNNs both in terms of accuracy and quantity of training data required.
