Implication

Computational modeling demonstrates rapid ion front acceleration during collision-free expansion in a semi-infinite plasma, indicating significant kinetic coupling with electron thermal motion.

Key Points

To calculate and characterize the collision-free expansion dynamics of a semi-infinite plasma expanding into an empty vacuum.
Calculated collisionless particle motion during the free expansion of a semi-infinite plasma boundary into vacuum conditions.
Demonstrated that the expanding ion front undergoes substantial acceleration away from the plasma core.
Showed that the final velocities attained by the accelerated ion front are comparable to the thermal velocity of the electrons.
