本文描述了一种能测量纳米尺度电子团簇分布的气体计数器。我们设计了一个电极系统，它能够从一个纳米级的无壁敏感体积中收集电子，并将它们转移到一个检测单个电子的计数器。在丙烷气体中的电子收集效率的测量证实，我们成功地收集了电子从壁的敏感体积，约20毫米宽，平均效率超过20%。(C)2001 Elsevier Science B.V.保留所有权利。
In this paper, we describe a gas counter able to measure electron cluster distributions in nanometric sized sites. We designed a system of electrodes that is able to collect electrons from a nanometric wall-less sensitive volume and to transfer them to a counter that detects single electrons. Measurements of electron collection efficiency in propane gas confirm that we successfully collected electrons from a wall-less sensitive volume, of about 20 mm width, with an average efficiency of more than 20%.
