标题： A study of the new hemispherical 9-inch PMT

摘要： 新型的9英寸直径的半球形光电倍增管（PMTs）来自海南中创光电技术有限公司（HZC）已被研究。观察到狭窄的渡越时间展宽（FWHM=2.35 ns），伴随小的非线性（5%时为750个光电子）和高增益（1E7）以及良好的单光电子（PE）分辨率。这种类型的11个PMT已部署并在中国科学院高能物理研究所（IHEP）的JUNO原型探测器中进行研究。 显示英文摘要

摘要： The new hemispherical photomultiplier tubes (PMTs) with 9 inch diameter from Hainan Zhanchuang Photonics Technology Co.,Ltd (HZC) have been studied. Narrow transit time spread (FWHM=2.35 ns) accompanied by small nonlinearity (750 photoelectrons at 5%) and high gain (1E7 ) with good single photoelectron (PE) resolution have been observed. 11 PMTs of this type are deployed and studied in the prototype detector for JUNO at IHEP, China.
