Indirect drive is a method used in fusion energy research where energy from lasers or ion beams is first absorbed by a material, typically a hohlraum, which then re-emits that energy to compress and heat the fusion fuel within. This technique allows for a more uniform and efficient application of energy to the fuel, enhancing the likelihood of achieving the conditions necessary for nuclear fusion. The indirect drive method is crucial in laser-driven and ion-beam-driven fusion experiments as it maximizes the effectiveness of the energy delivered to the target.
congrats on reading the definition of indirect drive. now let's actually learn it.
