Collisional Coupling in Counter-Streaming Laser-Produced Plasmas.
Abstract
The collisional mechanisms by which a high density expanding plasma transfers momentum to an ambient stationary background are examined, and applied to the example of a laser-produced plasma. Experimental measurements of collisional modification of the ion flow field confirm the treatment used for momentum transfer rates. A numerical model which simulates the collisional coupling of an expanding laser-produced plasma to a photoionized background is developed; the results are compared to laboratory data to assess the degree to which collisional coupling influences experimental interaction studies in which both collisionless and collisional effects may be important.
