论文摘要
这项工作报告了正在建设中的基于RPC的MUON散射断层扫描系统的经济高效，简单的前端读数和DAQ。已经利用了Nino Asics的阈值阈值财产，以通过提取位置信息来实现精确跟踪。对于原型RPC，已经证明了低成本FPGA进行事件选择和TOT测量，该原型由三个塑料闪烁体的宇宙射线hodoscope触发。通过分析RPC信号的波形，已经建立了输入脉冲宽度和TOT之间的关系。 FPGA已获得不同工作电压的TOT轮廓，并配备了高斯分布。它的标准偏差表示跟踪精度的估计值。
This work reports a cost-effective, simple front-end readout and DAQ of a RPC-based muon scattering tomography system under construction. The Time-over-threshold property of NINO ASICs has been exploited to achieve precise tracking by extraction of position information. The use of a low-cost FPGA for event selection and TOT measurement has been demonstrated for a prototype RPC which has been triggered by a cosmic ray hodoscope of three plastic scintillators. The relation between input pulse width and TOT has been established by analyzing the waveforms of the RPC signals. The TOT profile at different working voltages has been obtained by the FPGA and it has been fitted with the Gaussian distribution. Its standard deviation represents an estimate of the tracking precision.
