State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

Advanced Photonics Research, EarlyView.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

AMS-02 positron excess: new bounds on dark matter models and hint for primary electron spectrum hardening

, 2013
The data collected by ATIC, CREAM and PAMELA all display remarkable cosmic-ray-nuclei spectrum hardening above the magnetic rigidity $\sim$ 240 GV. One natural speculation is that the primary electron spectrum also gets hardened (possibly at $\sim 80$ GV)
