Massive Argon Space Telescope (MAST): a concept of heavy time projection chamber for gamma-ray astronomy in the 100 MeV --- 1 TeV energy range
摘要：
我们探讨的概念，液体氩时间投影室（TPC）的伽玛射线天文学在100 MeV - 1 TeV的能量范围。我们提出了一个基本的布局，这样的望远镜称为MAST。使用最后一代火箭，如猎鹰重型，有可能发射一个探测器的有效面积和微分灵敏度约一个数量级优于费米-LAT的。同时，MAST概念允许优异的角分辨率，根据能量比Fermi-LAT好3-10倍，以及良好的能量分辨率（在100 MeV下$\approx$为20%，在10 GeV - 1 TeV能量范围内为6- 10%）。我们表明，这样的望远镜将有助于在广泛的长期存在的天体物理问题。
英文摘要：
We explore the concept of liquid Argon time projection chamber (TPC) for gamma-ray astronomy in the 100 MeV --- 1 TeV energy range. We propose a basic layout for such a telescope called MAST. Using a last-generation rocket such as Falcon Heavy, it is possible to launch a detector with the effective area and the differential sensitivity about one order of magnitude better than the Fermi-LAT ones. At the same time, the MAST concept allows for an excellent angular resolution, 3-10 times better than the Fermi-LAT one depending on the energy, and good energy resolution ($\approx$ 20 % at 100 MeV and 6-10 % for the 10 GeV --- 1 TeV energy range). We show that such a telescope would be instrumental in a broad range of long-standing astrophysical problems.
