Abstract:
'The method of “weighting fields” gives an efficient way to compute the signal produced in a detector by a passing charged particle. Originally based on (quasi-)electrostatic approximations, this so called Ramo-Shockley theorem is heavily used to calculate signals in detectors based on ionisation, like gas detectors or silicon sensors. I will present an extension of the method to encapsulate the full extent of Maxwell’s equations, which renders it applicable to all devices that detect fields and radiation from charged particles. I will discuss possible applications of this method for the experimental study of cosmic rays, including consequences for the modelling of the detector signal produced by atmospheric showers.rnrnBased on https://doi.org/10.1016/j.nima.2020.164471'
