Abstract

The Dark MAtter Particle Explorer (DAMPE) instrument is a space-borne cosmic-ray detector, capable of measuring ion fluxes up to

\sim

500 TeV/n. This energy scale is made accessible through its calorimeter, which is the deepest currently operating in orbit. Saturation of the calorimeter readout channels starts occurring above

\sim

100 TeV of incident energy, and can significantly affect the primary energy reconstruction. Different techniques – analytical and machine-learning based – were developed to tackle this issue, focusing on the recovery of single-bar deposits, up to several hundreds of TeV. In this work, a new machine-learning technique is presented, which benefits from a unique model to correct the total deposited energy in DAMPE calorimeter. The described method is able to generalise its corrections for different ions and extend the maximum detectable incident energy to the PeV scale. This work is a continuation of the results presented in Stolpovskiyet al. (2022).

用暗物质粒子探测器对宇宙射线离子的量热计饱和进行机器学习校正：迈向PeV尺度

暗物质粒子探测器（DAMPE）仪器是一种太空宇宙射线探测器，能够测量高达~ 500 TeV/n的离子通量。这个能量刻度可以通过它的热量计获得，这是目前在轨道上运行的最深的热量计。在入射能量高于~ 100 TeV时，量热计读出通道开始出现饱和，并且可以显著影响一次能量重建。为了解决这个问题，开发了不同的技术（基于分析和机器学习的技术），重点是回收高达数百TeV的单棒矿床。在这项工作中，提出了一种新的机器学习技术，该技术得益于一种独特的模型来校正DAMPE量热计中的总沉积能量。所描述的方法能够推广其对不同离子的修正，并将最大可探测入射能量扩展到PeV尺度。这项工作是stolpovskiet al.（2022）中提出的结果的延续。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
