=== Plasma Heating and Transport === Plasma heating mechanisms are employed to increase plasma temperature and facilitate fusion reactions. Transport processes govern the movement of energy, particles, and momentum within the plasma. Important equations and mechanisms include: * '''Ohmic heating''': <math>P_{\text{Ohmic}} = \eta J^2</math> ** Purpose: Provides heating through plasma resistance, crucial for initiating and sustaining plasma currents in fusion devices. * '''Neutral beam injection''': <math>P_{\text{NBI}} = n \sigma v E_{\text{beam}}</math> ** Purpose: Injects high-energy neutral particles into the plasma to heat it and drive fusion reactions, contributing to efficient energy deposition. * '''Coulomb collisions''': <math>\frac{{\partial f}}{{\partial t}} = C(f)</math> ** Purpose: Models interactions between charged particles, essential for understanding plasma transport properties.
