Stagnation layers at the collision front between two laser-induced plasmas: A study using time-resolved imaging and spectroscopy

Collisionless Coupling of Ion and Electron Temperatures in Counterstreaming Plasma Flows

“…For the first time we show direct experimental measurements of free-streaming counter propagating plasma flows. Unlike previous experiments [1,15] it is clear from the flow velocity and electron density measurements that stagnation, a rapid decrease in the flow velocity and an increase in the local density, is not a factor for these conditions. A novel combination of collisional electron heating and collisionless ion heating is required to explain the observed temperature measurements.…”

Charge resolved electrostatic diagnostic of colliding copper laser plasma plumes

“…The collisionality parameter 23,27,30 ξ -determines which collision scenario will occur and is given by 23 .…”

“…More recently a large number of experiments in the visible spectral range, augmented by high speed imaging of CLPP have been reported [29][30][31][32][33] and target geometries utilized were either planar or wedge (varying angle) with plasma plumes streaming laterally or transversely. To date there have been very few reports on electrostatic diagnostic of CLPP 34,35 and no charge resolved electrostatic studies have yet been reported.…”

Ion emission in collisions between two laser-produced plasmas

“…To date we have reported a number of time resolved spectroscopic and imaging studies on the evolution of low energy laser produced colliding plasmas [18][19][20][21]. In this paper we change our focus to the ion emission from the colliding plasma system.…”
