用对计技术分析INO-ICAL的超高能μ子

Analysis of Ultra High Energy Muons at the INO-ICAL Using Pair-Meter Technique

Jaydip Singh, Srishti Nagu, Jyotsna Singh

摘要:

INO提出的ICAL探测器是一种大型地下磁化铁探测器。ICAL被设计用于使用磁谱仪重建μ子动量。使用磁铁的能量测量在TeV范围内的μ子失败,因为μ子在磁场中的角偏转可以忽略不计,μ子轨道变得几乎是直的。CCFR中微子探测器使用了一种测量TeV范围内μ子能量的新技术,称为对计技术。该技术通过测量μ子通过e $^+$和e $^-$对产生在铁量热计的许多层中沉积的能量来估计μ子能量。在这项工作中,我们已经进行了基于Geant 4的初步分析铁板,并证明了非常高的能量μ子(1 TeV-1000 TeV)的观测的可行性,在一个大质量的地下探测器作为一个对米。这一宽范围的能谱将有助于研究膝区的宇宙射线,并为当前和未来的超高能大气中微子实验提供对大气中微子通量的认识。

英文摘要:

The proposed ICAL detector at INO is a large sized underground magnetized iron detector. ICAL is designed to reconstruct muon momentum using magnetic spectrometers. Energy measurement using magnets fail for muons in TeV range, since the angular deflection of the muon in the magnetic field is negligible and the muon tracks become nearly straight. A new technique for measuring the energy of muons in the TeV range is used by the CCFR neutrino detector, known as the Pair-Meter technique. This technique estimates muon energy from measurements of the energy deposited by the muon in many layers of an iron-calorimeter through e$^+$ and e$^-$ pair production. In this work we have performed Geant4 based preliminary analysis for iron plates and have demonstrated the observational feasibility of very high energy muons (1TeV-1000TeV) in a large mass underground detector operating as a pair-meter. This wide range of energy spectrum will be helpful for studying the cosmic rays in the Knee region and an understanding of the atmospheric neutrino flux for the present and future ultra high-energy atmospheric neutrino experiments.
