Divertor physics is a specialized subfield within fusion plasma physics. It focuses on understanding and controlling the behavior of the plasma in the divertor region of magnetic confinement fusion devices. This field investigates complex phenomena including plasma-material interaction, particle and energy exhaust, impurity transport and screening, and the mitigation of extreme heat fluxes. Research in divertor physics is critical for developing robust and efficient plasma-facing components capable of withstanding the harsh environment, thereby ensuring the operational feasibility and longevity of future fusion reactors.
