固体核径迹探测器最精巧和最有实际意义的用途之一是病毒计数器。病毒计数器有时又叫DeBlois-Bean计数器,因两个美国人R.W.DeBlois和C.P.Bean发明这种仪器而得名。 DeBlois-Bean计数器的工作原理如图1所示。电化学容器B两边的悬浮液被具有原子核径迹微孔的膜片F隔开。膜片F的材料一般为高分子聚合物或云母,即固体核径迹探测器。微孔的直径大约0.8μm左右。这些微孔通常是用重带电粒子或由热中子诱发的裂变碎片辐照膜片,然后经化学蚀刻形成的。这种带裂片 One of the most ingenious and practical uses of solid nuclear track detectors is the virus counter. The virus counter is sometimes called the DeBlois-Bean counter, named after two Americans R.W.DeBlois and C.P.Bean invented the instrument. DeBlois-Bean counter works as shown in Figure 1. The suspension on both sides of the electrochemical vessel B is separated by a membrane F with micropore of the nuclear track. The material of the diaphragm F is generally a polymer or mica, that is, a solid nuclear track detector. The diameter of micropores is about 0.8 μm. These micropores are typically irradiated with heavy charged particles or fission fragments induced by thermal neutrons and then chemically etched. This strip with lobes
