Abstract

The SPD experiment for the NICA collider is currently under development. For efficient \(\pi \)- and \(K\)-mesons separation at the end-cap section of the SPD detector with a confidence level better than 3\(\sigma \), a Cherenkov ring imaging detector system based on focusing aerogel (FARICH) is proposed. In the spring of 2025, new aerogel samples of multilayer monoblocks were synthesized. A prototype FARICH detector was tested on the electron beam of the VEPP-4M complex. This paper presents the results of testing the prototype with the new aerogel samples, and describes the data processing from the experiment.

VEPP-4M综合体“电子束装置”FARICH原型试验数据处理

NICA对撞机的SPD实验目前正在开发中。为了实现SPD探测器端盖部分\(\pi \)介子和\(K\)介子的高效分离，且置信度大于3 \(\sigma \)，提出了一种基于聚焦气凝胶（FARICH）的Cherenkov环成像探测器系统。2025年春，合成了新的多层单块气凝胶样品。在VEPP-4M配合物的电子束上测试了FARICH探测器的原型。本文介绍了用新型气凝胶样品对样机进行测试的结果，并介绍了实验数据的处理过程。
