GIGAS：一组微波传感器阵列探测大范围空气簇射的分子韧致辐射
GIGAS: a set of microwave sensor arrays to detect molecular bremsstrahlung radiation from extensive air shower
摘要：
我们提出的GIGAS（千兆赫识别巨型空气簇射）微波无线电传感器阵列的EASIER项目（广泛的空气簇射识别与电子辐射计），部署在皮埃尔俄歇宇宙射线天文台的网站。这些新阵列的目的是探测分子韧致辐射的强度，这种强度是由于大气中超高能宇宙射线相互作用产生的大范围空气簇射的发展而产生的。在设计的设置中，传感器嵌入在皮埃尔·奥杰天文台的表面探测器阵列中，使我们能够使用地面的粒子信号来触发无线电系统。在C波段部署了一系列7个传感器，然后是61个传感器，随后是一系列新的14个更高灵敏度的C波段和L波段传感器。本文描述了这些阵列的设计、操作、校准和对广泛的空气簇射的灵敏度。
英文摘要：
We present the GIGAS (Gigahertz Identification of Giant Air Shower) microwave radio sensor arrays of the EASIER project (Extensive Air Shower Identification with Electron Radiometers), deployed at the site of the Pierre Auger cosmic ray observatory. The aim of these novel arrays is to probe the intensity of the molecular bremsstrahlung radiation expected from the development of the extensive air showers produced by the interaction of ultra high energy cosmic rays in the atmosphere. In the designed setup, the sensors are embedded within the surface detector array of the Pierre Auger observatory allowing us to use the particle signals at ground level to trigger the radio system. A series of seven, then 61 sensors have been deployed in the C-band, followed by a new series of 14 higher sensitivity ones in the C-band and the L-band. The design, the operation, the calibration and the sensitivity to extensive air showers of these arrays are described in this paper.
