Abstract

The particle identification system ASHIPH (Aerogel, SHIfter, PHotomultiplier) has been working in the KEDR experiment at the VEPP-4M

e^{+} e^{-}

collider (Budker INP, Novosibirsk), without interventions and upgrade, since 2014. The system consists of 160 aerogel Cherenkov counters containing aerogel with refractive index of 1.05. The ASHIPH system provides

π / K

separation in the momentum range from 0.6 to 1.5 GeV/

c

. The status of the system is presented. The long-term stability of aerogel counters in the KEDR experiment is studied. The use of the ASHIPH system in physics analysis is presented as well.

ashhiph Cherenkov在KEDR实验中反驳道

粒子识别系统ashhiph（气凝胶，SHIfter，光电倍增器）自2014年以来一直在VEPP-4M e+e−对撞机（Budker INP, Novosibirsk）的KEDR实验中工作，没有干预和升级。该系统由160个气凝胶切伦科夫计数器组成，内含折射率为1.05的气凝胶。ashhiph系统在0.6至1.5 GeV/c的动量范围内提供π/K分离。介绍了系统的现状。研究了气凝胶计数器在KEDR实验中的长期稳定性。介绍了ashhiph系统在物理分析中的应用。

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.
