Quasi-monoenergetic laser-plasma acceleration of electrons to 2 GeV
Laser-plasma accelerators of only a centimetre’s length have produced nearly monoenergetic electron bunches with energy as high as 1 GeV. Scaling these compact accelerators to multi-gigaelectronvolt… Expand
Effects of microstructure and composition on spall fracture in aluminum
Abstract Spall strength was measured as a function of composition and microstructure in three Al materials: a high-purity Al (Al HP), a commercial-purity Al (AA1100) and an alloy of Al containing 3… Expand
Cascade random-quasi-phase-matched harmonic generation in polycrystalline ZnSe
We experimentally and numerically investigated the cascade random-quasi-phase-matched harmonic generation in polycrystalline zinc selenide with tightly focused mid-infrared nanosecond laser pulses.… Expand
Range of plasma ions in cold cluster gases near the critical point
Abstract We measure the range of plasma ions in cold cluster gases by using the Petawatt laser at the University of Texas-Austin. The produced plasma propagated in all directions some hitting the… Expand
Temperature measurements of fusion plasmas produced by Petawatt-Laser-Irradiated D2 - (3)He or CD4 - (3)He clustering gases.
Two different methods have been employed to determine the plasma temperature in a laser-cluster fusion experiment on the Texas Petawatt laser. In the first, the temperature was derived from… Expand
Diagnostics improvement in the ABC facility and preliminary tests on laser interaction with light-atom clusters and p+11B targets
Abstract The diagnostics of particle flows in Inertial Confinement Fusion experiments is a delicate issue, due to the fast timescales and to the strong radiative electromagnetic contributions. This… Expand
Measurement of the plasma astrophysical S factor for the 3He(d,p)4He reaction in exploding molecular clusters.
The plasma astrophysical S factor for the 3He(d,p)4He fusion reaction was measured for the first time at temperatures of few keV, using the interaction of intense ultrafast laser pulses with… Expand
Microstructure dependence of dynamic fracture and yielding in aluminum and an aluminum alloy at strain rates of 2 × 106 s−1 and faster
Experiments investigating fracture and resistance to plastic deformation at fast strain rates (>106 s−1) were performed via laser ablation on thin sheets of aluminum and aluminum alloys. Single… Expand

Three types of neutron detectors (plastic scintillation detectors, indium activation detectors, and CR-39 track detectors) were calibrated for the measurement of 2.45 MeV DD fusion neutron yields… Expand
The Texas petawatt laser and current experiments
The Texas Petawatt Laser is operational with experimental campaigns executed in both F/40 and F3 target chambers. Recent improvements have resulted in intensities of >2×1021 W/cm2 on target.… Expand
