Abstract
Abstract
As demonstrated by the ATLAS New Small Wheel community with their MicroMegas (MM) design,
resistive electrodes are now used in different detector types within the Micro Pattern Gaseous
Detector family to improve their robustness. The extended form of the Ramo-Shockley theorem for
conductive media has been applied to a 1 MΩ/□ 2D resistive strip bulk MM to calculate
the signal spreading over neighbouring channels using an 80 GeV/c muon track. For this geometry,
the dynamic weighting potential was obtained numerically using a finite element solver by applying
a junction condition and coordinate scaling technique to accurately represent the boundary
conditions of a 10 × 10 cm2 active area. Using test beam measurements, the results of
this model will be used to benchmark this microscopic modelling methodology for signal induction
in resistive particle detectors.
