Magnetic control of tokamak plasmas through deep …
WEBFeb 16, 2022 · A newly designed control architecture uses deep reinforcement learning to learn to command the coils of a tokamak, and successfully stabilizes a wide variety of fusion plasma configurations.
DOE Explains...Tokamaks | Department of Energy
WEBA tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants.
Introduction to Tokamak Plasma Control - IEEE Xplore
WEBJul 3, 2020 · This paper provides an introduction to the problems of control of plasmas and plasma magnetic-confinement devices known as tokamaks. The basic science of fusion plasmas and objectives of plasma magnetic-confinement technologies are described.
Accelerating fusion science through learned plasma control
WEBFeb 16, 2022 · In a paper published today in Nature, we describe how we can successfully control nuclear fusion plasma by building and running controllers on the Variable Configuration Tokamak (TCV) in Lausanne, Switzerland. Using a learning architecture that combines deep RL and a simulated environment, we produced controllers that can both keep the plasma ...

Magnetic control of tokamak plasmas through deep …
WEBFeb 22, 2022 · A core challenge is to shape and maintain a high-temperature plasma within the tokamak vessel. This requires high-dimensional, high-frequency, closed-loop control using magnetic actuator coils, further complicated by the diverse requirements across a wide range of plasma configurations.
WEBcies are learned through interaction with a tokamak simulator and are shown to be directly capable of tokamak magnetic control on hardware, successfully bridging the ‘sim-to-real’ gap.
