我们研制了一种具有高气体增益和高位置分辨能力的新型正比计数管。它由一束细玻璃毛细管组成，入口和出口都有电极。毛细管直径为100 μm，长度为800 μm，在入口和出口之间施加电压时，每个毛细管中都发生了气体倍增。由此产生的正比计数器被发现，以操作高达104的增益没有击穿的发病，并有一个能量分辨率为26%的5.9千电子伏的X射线在气体增益为7000。其检测效率与传统的单线装置相同。
We have developed a new type of proportional counter with the capability of fine position resolution and high gas gain. It consists of a bundle of fine glass capillaries with electrodes on both the inlet and the outlet. The capillaries are 100 μm in diameter and 800 μm in length and gas multiplication was found to occur in each capillary with an applied voltage between the inlet and the outlet. The resulting proportional counter was found to operate up to a gain of 104without the onset of breakdown and had an energy resolution of 26% for 5.9 keV X-rays at a gas gain of 7000. Its detection efficiency was identical to a conventional single wire device.
