4300 m a.s.l.上残存初级质子的选择通过ARGO-YBJ实验
Selection of Surviving Primary Protons at 4300 m a.s.l. with the ARGO-YBJ experiment
摘要：
初级质子谱高达100 TeV的气球和卫星载仪器进行了调查。在这一能量范围以上，只有地面的空气簇射阵列才能用对核成分中等敏感的技术测量宇宙射线谱。在极高高度采用全覆盖方法的阵列可以实现远低于TeV区域的能量阈值，从而原则上允许利用气球/卫星的现有直接测量对初级宇宙线通量中测量的质子含量进行相互校准。位于羊八井宇宙线实验室（海拔4300米，中国西藏中国），在选择幸存的初级宇宙线质子进行了讨论。一个程序寻找一个非常陡峭的横向分布的准无伴事件。
英文摘要：
The primary proton spectrum up to 100 TeV has been investigated by balloon- and satellite-borne instruments. Above this energy range only ground-based air shower arrays can measure the cosmic ray spectrum with a technique moderately sensitive to nuclear composition. An array which exploits the full coverage approach at very high altitude can achieve an energy threshold well below the TeV region, thus allowing, in principle, the inter-calibration of the measured proton content in the primary cosmic ray flux with the existing direct measurements from balloons/satellites. The capability of the ARGO-YBJ experiment, located at the YangBaJing Cosmic Ray Laboratory (4300 m a.s.l., Tibet, P.R. China), in selecting the surviving primary cosmic ray protons is discussed. A procedure looking for quasi-unaccompanied events with a very steep lateral distribution is also presented.
