Coulomb explosions in plasma

Study of a dense hot plasma’s burning in Z-pinch devices with inertial-magnetic confinement

“…The use of equation ( 15) is valid under the condition that the thermalization times of energetic particles should be much less than the characteristic times of the thermonuclear burning process itself. The establishment of thermal equilibrium at T fin occurs over a time of the order of [7,22,23]:…”

“…In many works on the mathematical simulation of the action of femtosecond laser pulses on a solid target and plasma [5,6], it was found that at a sufficient power of such a pulse, the huge electric fields emerging at the focus of the femtolaser are able to remove all electrons from the focus zone. The area containing bare nuclei of the substance of laser target at the end of plasma pinch should expand in an extremely short time due to very large Coulomb repulsion forces among the same charged particles-bare nuclei of stripped atoms [7]. This so-called 'Coulomb explosion' of the end volume of the plasma creates a shock wave inside the plasma column, which will further compress and heat the plasma in the pinch.…”
