Z-pinch drivers

Definition

Z-pinch drivers are a type of plasma confinement technique that utilizes an electric current to compress plasma, which generates extreme temperatures and pressures. This method is particularly important for inertial confinement fusion (ICF) as it helps in achieving the conditions necessary for nuclear fusion by creating a high-density environment. The z-pinch approach allows for rapid compression of the plasma, making it a powerful tool in both research and potential energy generation applications.
