👉 The PDT fluid, or Pulse-Density Toroidal Transformer fluid, is a specialized liquid used in advanced tokamak devices like the International Thermonuclear Experimental Reactor (ITER) to generate and sustain the strong magnetic fields necessary for plasma confinement. This fluid, typically a mixture of deuterium and tritium gases, is pumped through a series of coils to create a toroidal magnetic field that traps and stabilizes the hot plasma, enabling nuclear fusion reactions. The PDT fluid's unique properties, including its high thermal conductivity and low viscosity, contribute to efficient plasma heating and current drive, making it crucial for achieving the conditions required for sustained fusion.
