在微模式气体探测器（MPGDs）上使用电阻技术为许多新的应用带来了一些优势，包括在高速率和高能粒子通量场景中的应用。最近在大面积探测器中使用这些技术使得有必要了解和表征这种类型的探测器的响应，以便优化或限制其生产中使用的参数，材料电阻率，带宽度或层厚度。所选择的值将取决于探测器放置的环境条件，以及对时间分辨率和增益的要求，从而提高探测器在每个给定应用中的性能。我们提出了两种不同的方法来计算电荷扩散通过不同的电阻拓扑的传播：一种是基于有限单元法（FEM）来求解我们特定的条形探测器方案中的电报方程，另一种是基于电荷扩散的半解析方法，用于确定电阻层中的电荷演化。
The use of resistive technologies on Micro-Pattern Gaseous Detectors (MPGDs) brings about several advantages for many new applications, including the ones in high rate and energetic particle flux scenarios. The recent use of these technologies in large area detectors makes necessary to understand and characterize the response of this type of detectors in order to optimize or constrain the parameters used in its production, material resistivity, strip width, or layer thickness. The values to be chosen will depend on the environmental conditions in which the detector will be placed, and on the requirements in time resolution and gain, improving the detector performance for each given application. We present two different methods to calculate the propagation of charge diffusion through different resistive topologies: one is based on a Finite Element Method (FEM) of solving the telegraph equation in our particular strip detector scheme, the other is based on a semi-analytical approach of charge diffusion and is used to determine the charge evolution in a resistive layer.
