本文描述了一种波长移动光纤读出闪烁正比计数器的特性，它能在0.2-100 keV的低能沉积下读出。在13.9keV处，探测器的能量分辨率为13%。示出了由初级电离的单电子产生的成比例的闪烁信号的检测的可能性。高压电路和光谱电子设备完全分离，消除了因击穿而导致的电子设备损坏的任何技术问题。即使是大尺寸的计数器也绝对没有麦克风噪音。它可以用于高振动或电磁场影响强烈的地区。这种低阈值计数器可用于低本底物理和X射线天文实验。采用这种设计，可以使探测器具有较大的尺寸和灵敏面积，并具有相当好的均匀性。
Characteristics of a scintillation proportional counter with wavelength-shifting (WLS) fiber optics readout for low energy deposition of 0.2-100 keV is described. The energy resolution of detector is 13% at 13.9 keV. The possibility of the detection of the proportional scintillation signal produced by the single electron of primary ionization is shown. A HV circuit and spectrometric electronics are totally separated form each other, that eliminates any technical problems of electronics damaging caused with a breakdown. There is no microphonic noise absolutely even for the large size counter. It can be utilized in areas with high vibration or with the strong influence of the electromagnetic field. This low threshold counter can be applied for the experiments in low-background physics and X-ray astronomy. With such a design the detector having large sizes and sensitive area with a fairly well uniformity is possible.
