💥Fusion plasma control with DL
To solve the global crisis, find sources of clean, limitless energy. For example, nuclear fusion, which powers the stars in the universe. On earth, atomic batteries can be used for this, breaking and fusing them under extreme conditions in a tokamak device - a vacuum surrounded by magnetic coils. In it the plasma radiation is hotter than the core of the Sun. The norm of the device in the operating mode is very difficult: the control system must coordinate many magnetic current coils and the voltage on them is several times less in order to achieve that the plasma never touches the walls of the vessel, which can lead to heat loss and, possibly, loss. Deep reinforcement learning has been successfully applied to this problem to create controllers that maintain plasma stability and stable control of various shapes.
Existing control systems for plasma complications and requiring rare control for each of the subsequent magnetic coils. Each controller uses algorithms to evaluate plasma properties in real time and measure magnet voltages. The architecture from the renowned Deep Mind AI Center and the Swiss Center for Plasma Research uses a single neural network to control all coils simultaneously, automatically judging which voltages are best for building plasma, especially with sensors.
