论文摘要
RPC检测器的常规读数方法使用两组放置在气体间隙两侧的正交读数条，以收集相反的极性信号以获得空间点。提出了一种使用反射信号的新读数方法，仅需要一组读取条。反射读数方法利用直接信号和反射信号的到达时间的差异来确定命中位置。引入定制的传输电缆以扩展反射信号的传播距离，以确保两个信号的足够分离。由于读取面板的一侧仅连接到费用板，因此反射读数方法可以增加几何认可并保存读取频道。本文显示了这种新型读取方法的实验设置和测试结果。证明可以通过用常用电子设备处理原始脉冲和反射脉冲的上升边缘来实现亚厘米的空间分辨率。
The conventional readout method of the RPC detector uses two sets of orthogonal readout strips placed at the both sides of the gas gap to collect signals of opposite polarities to obtain space points. A new readout method utilizing the reflected signals is proposed which only requires one set of readout strips. The reflection readout method utilizes the differences in the arrival time of the direct and reflected signals to determine the hit position. Customized transmission cables are introduced to extend the propagation distance of reflected signals to ensure sufficient separation of the two signals. Because only one side of the readout panel is connected to the FEE boards, reflection readout method can increase the geometrical acceptance and save the readout channels. Experimental setup and test results of this novel readout method is shown in this paper. It is demonstrated that a spatial resolution of sub centimeter can be achieved by processing the rising edges of the original and reflected pulses with commonly used electronics.
