GLAST是下一代高能伽玛射线天文台，旨在观测从10KeV到300GeV以上的波段的天体伽玛射线源。相对于之前的EGRET仪器，GLAST将具有更高的有效面积（6倍以上），更高的视场，能量范围和分辨率，提供前所未有的灵敏度进步（30倍或更多）。主要的科学目标是研究所有的伽马射线源，如耀变体、伽马射线暴、超新星遗迹、脉冲星、漫射辐射和未识别的高能源。在过去的几年里，大面积望远镜（LAT）跟踪器的建造和测试一直是一项巨大的努力，涉及来自意大利INFN许多部门和工业合作伙伴的数十人。在LAT建设的所有步骤中，都进行了硬件、探测器和读取电子设备的环境和性能测试。所得到的LAT性能优于原始科学提案所要求的性能，表明了意大利团队努力的质量。在本文中，我们总结了LAT的构建和测试工作流程，并介绍了它的主要成果。
GLAST is a next generation high-energy gamma-ray observatory designed for making observations of celestial gamma-ray sources in the energy band extending from 10KeV to more than 300GeV. Respect to the previous instrument EGRET, GLAST will have a higher effective area (six times more), higher field of view, energy range and resolution, providing an unprecedented advance in sensitivity (a factor 30 or more). The main scientific goals are the study of all gamma-ray sources such as blazars, gamma-ray bursts, supernova remnants, pulsars, diffuse radiation, and unidentified high-energy sources. The construction and test of the Large Area Telescope (LAT) tracker, has been a great effort during the past years, involving tens of people from many Italian INFN sections and industrial partners. Environmental and performance tests of the hardware, detectors and reading electronics, have been carried on during all the steps of the LAT construction. The resulting LAT performance are better than the ones required by the original science proposal, demonstrating the quality of the italian group effort. In this article we summarize the LAT construction and test workflow, presenting its main results.
