摘要:

为SIDDHARTA-2实验开发了一种基于塑料闪烁体探测器的光度监测器,旨在对K介子原子进行高精度测量,并于2020年安装在LNF的DAFNE $e^+e^-$对撞机上。该系统的主要目标是通过测量由φ介子衰变产生的$K^+K^-$关联对的速率来提供DAFNE装置的瞬时和积分亮度。这项任务需要DAQ信号的精确定时,以及低于1 ns的定时分辨率,以便将$K^\pm$信号与DAFNE的$e^+e^-$碰撞期间产生的背景最小电离粒子(MIP)分离。本文介绍了DAFNE光度监测器的概念及其实验室特性和第一批结果。

英文摘要:

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.
