A New Detection Technique For The Observation of ZeV Cosmic Rays

小行星9527421 在闪烁体和切伦科夫阵列以及蝇眼中观测到了能量超过10 GeV的最高能量宇宙线原色产生的簇射。 前者探测簇射成分，后者探测它们在大气中产生的荧光。 这两种技术都具有有限的孔径，由于成本原因不太可能大幅增加。 这笔赠款资助了一种新的方法，可以提供比传统方法更大的孔径，具有可比的分辨率，成本明显低于传统方法。 计算表明，簇射粒子发出的切伦科夫光强度足以产生可检测的信号（甚至可能在白天！）在地面上排列的非成像平面探测器中。 在各种候选技术中，单晶CZ-Si太阳能电池板将是研究的焦点，这些技术容易获得并且相对便宜。 将通过测量太阳能电池板和其他可能的探测器的灵敏度，并在CASA/MIA/HiRes宇宙射线探测器系统所在地安装一小组装有仪器的电池板，以探测与之同时出现的流星雨，来检验这一新想法。

9527421 Kieda Showers produced by the highest energy cosmic ray primaries, with energy above 10 GeV have been observed in scintillator and Cerenkov arrays and the Fly's Eye. the former detects shower components, the latter their fluorescence produced in the atmosphere. Both techniques have limited aperture not likely to be substantially increased because of cost. This grant funds a new approach that may provide substantially larger aperture with comparable resolution at significantly lower cost than is possible with conventional methods. Calculations show that Cerenkov light emitted by the shower particles is intense enough to produce detectable signals (perhaps even in daylight!) in non-imaging planar detectors arrayed on the ground. Of the various candidate technologies, single- crystal CZ-Si solar panels, will be the focus of the research, those being readily available and relatively inexpensive. This novel idea will be tested with measurements of the sensitivity of the solar panels and other possible detectors and with an instrumented small set of panels at the site of the CASA/MIA/HiRes cosmic-ray detector system to detect showers in coincidence with it. ***
