论文摘要
我们介绍了分析计算,有限元分析建模以及对CMS MUON系统中GE2/1 Triple-Gas电子乘数检测器的不同潜在条形几何形状和读取板的尺寸的施加电容的物理测量。该研究的主要目标是找到最大程度地减少施加电容的配置,从而最大程度地提高检测器的信噪比。我们发现两种计算方法之间的协议在1.5--4.8%的水平上,计算和测量之间的平均水平为17%。一半的带状长度和两倍的带宽度的配置导致比原始配置减少27-29%,同时使条带不变。现在,我们对GE2/1检测器的所有八种模块类型都采用了此设计修改,并将使用这种新的脱带设计产生最终检测器。
We present analytical calculations, Finite Element Analysis modeling, and physical measurements of the interstrip capacitances for different potential strip geometries and dimensions of the readout boards for the GE2/1 triple-Gas Electron Multiplier detector in the CMS muon system upgrade. The main goal of the study is to find configurations that minimize the interstrip capacitances and consequently maximize the signal-to-noise ratio for the detector. We find agreement at the 1.5--4.8% level between the two methods of calculations and on the average at the 17% level between calculations and measurements. A configuration with halved strip lengths and doubled strip widths results in a measured 27--29% reduction over the original configuration while leaving the total number of strips unchanged. We have now adopted this design modification for all eight module types of the GE2/1 detector and will produce the final detector with this new strip design.
