摘要

为了提高欧洲核子研究中心(CERN)大型强子对撞机(LHC) ALICE实验的电子识别和触发能力，设计了一个跃迁辐射探测器(TRD)。在0.9 ~ 2.4 GeV/c的动量范围内，用不同的分析方法对TRD原型的介子抑制进行了测试。我们研究了由箔片、纤维和泡沫组成的不同类型的散热器的性能。

Prototype tests for the ALICE transition radiation detector

A Transition Radiation Detector (TRD) has been designed to improve the electron identification and trigger capability of the ALICE experiment at the Large Hadron Collider (LHC) at CERN. We present results from tests of a prototype of the TRD concerning pion rejection for different methods of analysis over a momentum range from 0.9 to 2.4 GeV/c. We investigate the performance of different radiator types, composed of foils, fibres and foams.
