我们提出了一种新的空气荧光和切伦科夫探测器ASHRA。ASHRA第一阶段探测器由1+1/3观测站组成，安装在距离30-40公里的山区。它保证了中微子的大靶质量和TeV γ射线的低能量阈值。观测站由12台广角高精度望远镜组成，可全天候观测。每个望远镜的视场为50度。× 50度光点尺寸分辨率为1弧分。为了实现ASHRA望远镜的概念，我们新应用了在其他领域成熟的以下技术：i）优化的贝克-纳恩光学系统，以保持优于1弧分。分辨率为50 °。视场，ii）静电透镜图像增强管（IIT），其分辨率与上述光学器件的分辨率相匹配，iii）具有快速图像快门的门控IIT，以及iv）从上述IIT中读取触发图像的CMOS图像传感器。
We propose a new air fluorescence and Cerenkov detector ASHRA. The ASHRA phase-1 detector consists of 1+1/3 observational stations installed at the distance of 30–40 km in a mountain site. It ensures the large target mass for neutrinos and low-energy threshold for TeV gamma rays. The observational station is composed of 12 wide-angle high-precision telescope, which can cover completely all-sky view. Each telescope has a field-of-view of 50 deg. × 50 deg. and spot size resolution of 1 arcmin. To realize the ASHRA telescope concept, we newly apply the following techniques matured in the other fields: i) Baker-Nunn optics optimized to keep better than 1 arcmin. resolution in 50 deg. field of view, ii) electrostatic lens image intensifier tube (IIT) with the resolution matched with that of the above optics, iii) gated IIT with a fast image shutter, and iv) CMOS image sensor which read triggered images out of the above IIT.
