摘要:

空气簇射射电探测技术的最新进展为未来的宇宙射线射电探测器铺平了道路。数字无线电阵列可以测量空气簇射能量及其最大深度,其分辨率可与领先的光学探测方法相媲美。关于宇宙射线射电仪器的剩余挑战之一是准确估计其效率和孔径。我们提出了一个概率模型来应对这一挑战。我们使用该模型来估计通卡-雷克斯无线电阵列的效率和孔径。该模型的基础是一个参数化的无线电足迹和概率处理的检测过程中的天线和阵列的水平。通过这种方法,我们可以估计空气簇射的探测效率作为其到达方向,能量和在地面上的影响点的函数。此外,在我们的概率方法中,空气簇射检测过程的不同阶段之间的透明内部关系使得能够估计效率的不确定性,因此,无线电阵列的孔径。该模型的细节将在贡献中介绍。

英文摘要:

The recent progress in the radio detection technique for air showers paves the path to future cosmic-ray radio detectors. Digital radio arrays allow for a measurement of the air-shower energy and depth of its maximum with a resolution comparable to those of the leading optical detection methods. One of the remaining challenges regarding cosmic-ray radio instrumentation is an accurate estimation of their efficiency and aperture. We present a probabilistic model to address this challenge. We use the model to estimate the efficiency and aperture of the Tunka-Rex radio array. The basis of the model is a parametrization of the radio footprint and a probabilistic treatment of the detection process on both the antenna and array levels. In this way, we can estimate the detection efficiency for air showers as function of their arrival direction, energy, and impact point on the ground. In addition, the transparent internal relationships between the different stages of the air-shower detection process in our probabilistic approach enable to estimate the uncertainty of the efficiency and, consequently, of the aperture of radio arrays. The details of the model will be presented in the contribution.
