论文摘要
基于塑料闪烁探测器的光度监测器已为Siddharta-2实验开发，旨在对Kaonon Atoms进行高精度测量，并于2020年在LNF的Dafne $ E^+E^ - $ Collider上安装在LNF（Laboratori nazionali di Frascati，Infn，Infn）。该系统的主要目标是通过测量Phi Meson Decay发出的$ k^+k^ - $相关对的速率来提供DAFNE设施的瞬时和集成的光度。此任务需要DAQ信号的准确时机以及低于1NS的定时分辨率，以便将$ k^\ pm $信号从$ e^+e^+e^ - $ collisions在dafne collisions中产生的最小电离粒子（MIPS）中解开。在本文中，介绍了亮度监控概念及其实验室表征和达夫内的第一个结果。
A luminosity monitor, based on plastic scintillator detectors, has been developed for the SIDDHARTA-2 experiment aiming to perform high precision measurements of kaonic atoms and was installed in 2020 on the DAFNE $e^+e^-$ collider at LNF (Laboratori Nazionali di Frascati, INFN). The main goal of this system is to provide the~instantaneous and integrated luminosity of the DAFNE facility by measuring the rate of $K^+K^-$ correlated pairs emitted by the phi meson decay. This task requires an accurate timing of the DAQ signals, as well as timing resolution below 1ns, in order to disentangle the $K^\pm$ signals from the background minimum ionizing particles (MIPs) produced during the $e^+e^-$ collisions at DAFNE. In this paper the luminosity monitor concept as well as its laboratory characterization and the first results inside DAFNE are presented.
