摘要 中意合作羊八井ARGO实验采用大型RPC阵列探测广延大气簇射事例 ,本文报告了该探测阵列初期建设进展状况及测试运行的包含 16个CLUSTER的局部阵列性能 ,并探讨由此阵列所采集数据重建后的事例芯位、到达方向与角分辨等 .初步测试结果表明RPC阵列可很好地在高海拔、低气压条件下正常运行 . The Sino-Italian collaboration YBJ-ARGO experiment is under construction at the Yang Bajing High Altitude Cosmic Ray Laboratory(Tibet,China,4300m a.s.l.,606g/cm2).About 693m2 of preliminary carpet detector have been instrumented and put into operation for calibration runs devoted to test the performance of the individual components and their integrated operation.Events collected with a 'shower mode' trigger have been recorded to check the consistency of physics data.The performance and characteristics of a preliminary carpet detector are analyzed using its test run data at the high altitude conditions.Shower reconstruction algorithms are described together with the results after time offset correction.Results of the test run show the importance of the time correction for data analysis,and some results concerning detector calibration,azimuth angle distribution,zenith angle distribution and angular resolution are presented.
