论文摘要
基于FCAL合作于2019年发表的一篇论文，此演讲正在最新该协作的努力，以设计高度紧凑的热量表的原型，以在未来的$ E^+E^ - $ Colleders上启动检测器的非常向前的区域。基于亚毫米厚检测器平面的发光计原型，用一个能量1-5 GEV测试。测量包含八个检测器平面的原型的有效莫利半径为（8.1 +/- 0.1（stat。）+/- 0.3（syst。））mm，结果通过蒙特卡洛模拟很好地复制了结果。
Based on a paper published in 2019 by the FCAL Collaboration, this talk is giving an update of the Collaboration's effort to design prototype of highly compact calorimeter to instrument the very forward region of a detector at future $e^+e^-$ colliders. A luminometer prototype, based on sub-millimeter thick detector planes, is tested with an electron-beam of energy 1-5 GeV. The effective Moliere radius of the prototype comprising eight detector planes was measured to be (8.1 +/- 0.1 (stat.) +/- 0.3 (syst.))mm, and the result is well reproduced by the Monte Carlo simulation.
