We report self-injected quasi-monoenergetic (5% spread FWHM) acceleration of electrons to 2.0 ± 0.1 GeV by 0.6 PW-laser-driven wakefield acceleration in pure He plasma of density 5×1017 cm−3. Electron bunches diverge ∼0.5mrad, and contain ∼60 pC.
We report electron acceleration to 1.25 GeV by petawatt-laser-driven wakefield acceleration at plasma density 5×1017 cm3. Electron beams are dark-current-free, quasi-monoenergetic, highly collimated (<1mrad divergence), contain tens of pC and have excellent pointing stability.
We report observation of electron self-injection and acceleration in a plasma accelerator driven by the Texas petawatt laser at 1017 cm−3 plasma density, an order of magnitude lower density than previous self-injected laser-plasma accelerators.
This study calculated the stresses and deformations of the acrylic tanks used in neutrino experiment under dynamic loads and evaluated the safety level of those tanks. The diameters of those large t tanks are ??3m and the thickness of their walls are only 10mm. The measured mechanical properties are: EB=2.95GPa ??8%, SY=77.92 ??7%, SU= 102.13MPa ??12%. The stress distributions of the tanks were simulated...
This paper considers an alternative strategy to speed up the circuit simulation. This strategy considers characteristics of simulator users' behaviors and involves two techniques, the incremental simulation and simulation-on-demand (SOD). These techniques are implemented in an "Interactive Simulation Environment" to dramatically accelerate the simulation speed in most practical cases. Also,...
