在欧洲共同体委员会的一个研究计划框架内，欧洲核子研究中心的参考辐射设施最近提供了一个混合高能辐射场，模拟在民航高度约10公里处发现的辐射场。为了校准辐射探测器并研究它们对高能中子的响应，使用了五种不同的仪器，配备了低压组织等效比例计数器（TEPC）和一个重组室（REM-2）进行了一系列测量。欧洲核子研究中心的参考辐射场是由2/3质子和1/3介子混合的初级光束与铜靶反应产生的，并通过混凝土屏蔽进行调节。本文总结了五种TEPC仪器和rem2所取得的结果，并讨论了它们的特点。
Within the framework of a research program of the Commission of European Communities the reference radiation facility at CERN provided recently a mixed high-energy radiation field simulating the one found at civil aviation altitudes of about 10 km. In order to calibrate radiation detectors and to investigate their response to high-energy neutrons a series of measurements using five different instruments equipped with low pressure tissue-equivalent proportional counter (TEPC) and one recombination chamber (REM-2) has been carried out. The reference radiation field at CERN was produced by reactions of a primary beam mixed of 2/3 protons and 1/3 pions with a copper target and moderated by a concrete shielding. The paper summarizes the results obtained with the five TEPC instruments and the REM-2, and discusses their characteristics.
