磁化铁量热计探测器（ICAL），建议在印度的中微子天文台（INO）建造，旨在研究大气中微子振荡。ICAL探测器被优化以测量μ子动量、方向和电荷。一个基于GEANT 4的软件包已经开发的INO合作模拟ICAL几何形状和粒子通过探测器的传播。利用卡尔曼滤波算法对模拟的μ子径迹进行了重建。在这里，我们提出了第一个研究的ICAL探测器的μ子使用这个模拟包，以确定μ子的动量和方向的分辨率，以及它们的重建和电荷识别效率的响应。对中心区1-20 GeV/c μ子，角分辨约为1度，动量分辨平均为9- 14%，重建效率约为80%，电荷识别正确率约为98%。
The magnetised Iron CALorimeter detector (ICAL), proposed to be built at the India-based Neutrino Observatory (INO), is designed to study atmospheric neutrino oscillations. The ICAL detector is optimized to measure the muon momentum, its direction and charge. A GEANT4-based package has been developed by the INO collaboration to simulate the ICAL geometry and propagation of particles through the detector. The simulated muon tracks are reconstructed using the Kalman Filter algorithm. Here we present the first study of the response of the ICAL detector to muons using this simulations package to determine the muon momentum and direction resolutions as well as their reconstruction and charge identification efficiencies. For 1–20 GeV/c muons in the central region of the detector, we obtain an average angle-dependent momentum resolution of 9–14%, an angular resolution of about a degree, reconstruction efficiency of about 80% and a correct charge identification of about 98%.
