End-to-End Multiphysics Simulation of PhotoelectricCharge Management: Application to Free-falling Test Masses

We present a simulation for the charge management process in its entirety using the COMSOL Multiphysics modeling software.

We present a simulation for the charge management process in its entirety using the COMSOL Multiphysics modeling software. We recover the UV absorption map inside GRS, the quantum yield (QY), and work functions of both test mass and electrode housing surfaces through an MCMC fit of the model and empirical AY results.
