Controller with Integrated Machine Learning Tweaks Fusion Plasmas in Real Time

Department of Energy, Office of Science — Mon, 16 Dec 2024 20:55:07 EST

The conditions for high fusion performance in fusion devices can result in damaging energy bursts called edge-localized modes (ELMs). ELMs can be stabilized through small adjustments to the magnetic confinement field, but this approach is usually limited to manual, preprogrammed responses. In this research, scientists integrated machine learning with adaptive control to achieve real-time adjustment capable of responding to the dynamic conditions of a fusion plasma in the DIII-D National Fusion Facility and Korea Institute of Fusion Energy KSTAR tokamaks.

The programs held this year, including the QIS & Engineering High School-Level Program, QIS 102: Quantum Computing Summer School, and QIS 303: Quantum Error Mitigation, reached more than 170 participants worldwide, from students who just completed their first year of high school to full-fledged QIS researchers -- and enthusiastic learners from every level of expertise in between.

Cooling with Electroluminescent Semiconductors

Department of Energy, Office of Science — Fri, 13 Dec 2024 18:20:09 EST

: In an LED, electroluminescence creates light through charge carriers that cause the semiconductor to emit photons. This emission can require more energy than is present in the semiconductor, and this excess energy comes from heat around the semiconductor. This makes a semiconductor into a cooling device. In this study, researchers proposed a way to improve the performance of this electroluminescent cooling by using multilayer semiconductors.
