为了提高电阻板室（RPC）亚毫米波段的空间分辨力，提出了一种新的、非常有前途的读出方法。该方法是基于读出的信号在石墨电极中传播，这是使用分布电阻电容模型在SPICE模拟。结果表明，只有通过适当的信号处理，扩散过程中良好的空时相关性才是可能的。测试了三个具有新布局和专用电子设备的RPC探测器。测量的空间分辨率为几百μm量级。
A new very promising read out, in addition to the well-known charge centroid method, is proposed for improving the space resolution in the Resistive Plate Chamber (RPC) in the sub-millimeter range. The method is based on the read out of the signal propagating in the graphite electrode which was simulated using a distributed resistance–capacitance model in SPICE. The results show that a good space-time correlation in the diffusion process is only possible by suitable signal processing. Three RPC detectors with the new layout and dedicated electronics were tested. The measured space resolution was in the order of a few 100μm.
