摘要:

水切伦科夫探测器(WCD)是使用单粒子技术探测10 GeV - 1 TeV能量范围内伽马射线暴的有效探测器,因为它们对高能光子在大气中级联时产生的低能次级光子敏感。大孔径伽玛射线暴天文台(LAGO)在高海拔地区(海拔4500米以上)运行WCD阵列。在玻利维亚、墨西哥和委内瑞拉,计划扩展到秘鲁。详细的操作和稳定性,这些WCD在偏远地区的高背景率的粒子将被详细说明,并与模拟。还将介绍由于在高空运行、大气影响和太阳活动以及可能的硬件改进而产生的具体问题。

英文摘要:

Water Cherenkov Detectors (WCD) are efficient detectors for detecting GRBs in the 10 GeV - 1 TeV energy range using the single particle technique, given their sensitivity to low energy secondary photons produced by high energy photons when cascading in the atmosphere. The Large Aperture GRB Observatory (LAGO) operates arrays of WCD in high altitude sites (above 4500 m a.s.l.) in Bolivia, Mexico and Venezuela, with planned extension to Peru. Details on the operation and stability of these WCD in remote sites with high background rates of particles will be detailed, and compared to simulations. Specific issues due to operation at high altitude, atmospheric effects and solar activity, as well as possible hardware enhancements will also be presented.
