论文摘要
在各种应用中，宇宙射线雄性被认为是一种非惯性辐射探头。为了在工程应用中利用宇宙射线muons，必须知道两个重要数量的轨迹和动量。使用具有较高空间分辨率的两个检测器阵列轻松地重建了MUON轨迹。但是，如果不部署大型且昂贵的光谱仪（例如电磁磁铁），难以实现MUON动量的精确测量。在这里，我们提出了一种使用多层加压气体Cherenkov辐射器来估计万能动量的新方法。这是准确的，便携的，紧凑的（<1M3），并且很容易与现有的MUON探测器结合，而无需既笨重的磁性也不需要飞行时间。结果表明，不仅我们的新哑光光谱仪可以在0.1至10.0 GEV/c的动量范围内测量 +-0.5 GeV/c的MUON动量，而且我们也可以以很高的精度重建宇宙MUON光谱（〜90％）。
Cosmic ray muons have been considered as a non-conventional radiation probe in various applications. To utilize cosmic ray muons in engineering applications, two important quantities, trajectory and momentum, must be known. The muon trajectories are easily reconstructed using two-fold detector arrays with a high spatial resolution. However, precise measurement of muon momentum is difficult to be achieved without deploying large and expensive spectrometers such as solenoid magnets. Here, we propose a new method to estimate muon momentum using multi-layer pressurized gas Cherenkov radiators. This is accurate, portable, compact (< 1m3), and easily coupled with existing muon detectors without the need of neither bulky magnetic nor time-of-flight spectrometers. The results show that not only our new muon spectrometer can measure muon momentum with a resolution of +-0.5 GeV/c in a momentum range of 0.1 to 10.0 GeV/c, but also we can reconstruct cosmic muon spectrum with high accuracy (~90%).
