Heuristic Observation with All-sky High Resolution Air-shower detector

ASHRA(全天巡天高分辨率空气簇射探测器)是一个项目，旨在建造一个非传统的光学望远镜综合体，它可以拍摄非常宽的视场，覆盖80%的天空，但角度分辨率只有几角分，使用像增强器和CMOS技术对蓝色到紫外光敏感。该项目的主要目的是观测大气层中极高能量宇宙射线的横向和纵向发展过程中的切伦科夫光和荧光光。在2005年7月莫纳罗亚的土地用途获得批准后，我们立即入驻该地块并开始开发。在2005年7月底完成了莫纳罗亚工地2 419平方米区域的平整工作后，电力线路和变压器的安装工作一直持续到9月初。我们在从日本获得材料后，于2005年10月开始建造探测器。…最近(2005年12月中旬)，在莫纳罗阿工地的八个混凝土建筑桥墩上建造并安放了几个带有电动卷帘门、用于保持气密性的亚克力板窗以及隔热墙和地板的避难所。在避难所里，集光器的光学元件已经安装完毕。2005年12月，我们使用Hess小组安装的Ashra光收集器对莫纳罗亚岛的夜空背景通量进行了评估，并将其与拉帕尔马和纳米比亚的背景一致。从星光观测，我们对光校正效率的了解准确度在5%的水平内。在莫纳罗阿工地的避难所里，光收集器的土木工程建设已经完成。我们正在一步一步地进行设备安装和具体观察，以增强科学影响。较少

Ashra (All-sky Survey High Resolution Air-shower detector) is a project to build an unconventional optical telescope complex that images very wide field of view, covering 80% of the sky, yet with the angle resolution of a few arcmin, sensitive to the blue to UV light with the use of image intensifier and CMOS technology. The project primarily aims to observe Cherenkov and fluorescence lights from the lateral and longitudinal developments of very-high energy cosmic rays in the atmosphere. It can also be used to monitor optical transients in the wide field of sky.After approval of the land usage at the Mauna Loa site in July 2005, we immediately occupied the site and began development. After finishing the grading work for the area of 2,419m^2 at the Mauna Loa site at the end of July 2005, installation of electrical power lines and transformers was performed until the beginning of September. We started the construction of the detector in October 2005 after receiving materials from Japan. … More Currently, (mid December 2005) a few shelters having motorized rolling doors, acrylic plate windows to maintain air-tightness, and heat-insulating walls and floors have been constructed and positioned on eight construction piers of concrete blocks at the Mauna Loa site. In the shelters, the optical elements of the light collectors have been already installed. The optical performance were checked and adjusted to be optimum with star light images from the pilot observation.In December 2005, we evaluated the night sky background flux on Mauna Loa using the Ashra light collector installed and aligned in a shelter to be consistent with the background in La Palma and Namibia by the HESS group. From the star light observations, our understanding of the light correction efficiency to be accurate within 5% level.The civil engineering construction of light collectors, in shelters at the Mauna Loa site has been completed. We are performing device installation and specific observation in a step-by-step way to enhance the scientific impacts. Less
