We report the first direct measurement of temporally and spatially resolved plasma temperatures at a shock as well as its spatial structure and propagation in laser-produced counter-streaming plasmas. Two shocks are formed in counter-streaming collisionless plasmas early in time, and they propagate opposite directions. This indicates the existence of counter-streaming collisionless flows to keep exciting the shocks, even though the collisional effects increase later in time. The shock images are observed with optical diagnostics, and the upstream and downstream plasma parameters of one of the shocks are measured using Thomson scattering technique.

“…LTS has been widely used for diagnostics of high temperature, high density plasmas, 12,13 as well as low pressure nonequilibrium discharges. 8,9 Kono et al 8 performed measurements in 2.45 GHz microwave microdischarges, sustained in a 100 m gap at atmospheric pressures of air or a He/ N 2 ͑5%͒ mixture. Noguchi et al 7 used LTS to measure the electron temperature and density in a pulsed ͑10 kHz͒ dc argon microdischarge at a pressure of 50 Torr.…”

“…[14][15][16][17][18][19][20] LTS experiments in microdischarges are challenging because of the low signal and excessive stray light. Hassaballa et al 9 studied a pulsed dc ͑20 kHz͒ microdischarge in Ne/ Ar ͑10%͒ mixture at pressures of 100-300 Torr. Other groups have also performed LTS in different types of microdischarges.…”

“…1 (b). Because the basic configuration of the TGS has been already reported in many studies [4,5,17], only a brief explanation is presented here. The TGS mainly comprises six achromatic lenses ( f = 250 mm, diameter 46 mm), three diffraction gratings (2400 lines/mm), an entrance slit (width 0.2 mm), a physical notch filter (width 0.5 mm) at the first image plane, and an intermediate slit (width 0.2 mm) at the second image plane.…”

Electron density (n e ) and electron temperature (T e ) measurements were performed via the plasma assembly for nonlinear turbulence analysis (PANTA) using the laser Thomson scattering technique. The second harmonic of Nd:YAG laser (λ = 532 nm) and an intensified charge-coupled device were used as a light source and a detector, respectively. Plasmas in PANTA were generated with Ar gas in a pressure range of 1 -5 mTorr. The range of the applied magnetic field was 600 -1500 G. At the center of the plasma, n e and T e ranged (4 -20) × 10 18 m −3 and 0.8 -3 eV, respectively. Further, n e monotonically increased and T e monotonically decreased with the increasing gas pressure and magnetic field.
