论文摘要
Da $φ$ ne对撞机的Siddharta-2实验旨在执行第一个Kaonic氘X射线过渡到基本水平的测量，并在几个EV的级别上进行系统误差。为了实现这一具有挑战性的目标，实验设备配备了分布在其低温气体目标周围的384个硅漂移探测器（SDDS）。 Siddharta-2合作开发的SDD适用于高精度的Kaonic原子光谱，这要归功于它们的高能量和时间分辨率与它们的辐射硬度相结合。必须对每个检测器的能量响应进行校准和监测，以保持系统误差，因为诸如增益波动之类的过程在2-3 eV的水平下。本文介绍了Siddharta-2校准方法，该方法在实验的初步阶段进行了优化，该方法在Da $φ$ ne Collider的真实背景条件下，这是保证长期数据采集系统的高精度光谱性能的基本工具，如Kaonic Deuterium测量所必需的。
The SIDDHARTA-2 experiment at the DA$Φ$NE collider aims to perform the first kaonic deuterium X-ray transitions to the fundamental level measurement, with a systematic error at the level of a few eV. To achieve this challenging goal the experimental apparatus is equipped with 384 Silicon Drift Detectors (SDDs) distributed around its cryogenic gaseous target. The SDDs developed by the SIDDHARTA-2 collaboration are suitable for high precision kaonic atoms spectroscopy, thanks to their high energy and time resolutions combined with their radiation hardness. The energy response of each detector must be calibrated and monitored to keep the systematic error, due to processes such as gain fluctuations, at the level of 2-3 eV. This paper presents the SIDDHARTA-2 calibration method which was optimized during the preliminary phase of the experiment in the real background conditions of the DA$Φ$NE collider, which is a fundamental tool to guarantee the high precision spectroscopic performances of the system over long periods of data taking, as that required for the kaonic deuterium measurement.
