标题： Powerful nanosecond light sources based on LEDs for astroparticle physics experiments

摘要： 基于LED的强大纳秒级光源已开发用于在粒子天体物理学实验中使用。这些光源要么使用超亮蓝光LED矩阵，要么采用新一代高功率蓝光LED。研究表明，这种光源每脉冲的光产额可达10**10至10**12个光子，并具有非常快的发光动力学特性。所述光源对于切伦科夫和闪烁体探测器的校准系统非常重要。所开发的光源目前已经在若干粒子天体物理实验中成功应用，例如：TUNKA广延大气簇射实验、贝加尔中微子实验等。 显示英文摘要

摘要： Powerful nanosecond light sources based on LEDs have been developed for use in astroparticle physics experiments. The light sources use either matrixes of ultra bright blue LEDs or a new generation high power blue LEDs. It's shown that such light sources have light yield of up to 10**10 - 10**12 photons per pulse with very fast light emission kinetics. The described light sources are important for use in calibration systems of Cherenkov and scintillator detectors. The developed light sources are currently used successfully in a number of astroparticle experiments, namely: the TUNKA EAS experiment, the Baikal neutrino experiment etc.
