Sumario:Linac4 Drift Tube Linac (DTL) cavities will be equipped with Post Couplers (PCs) for field stabilization. The study presented in this paper starts with the analysis of 2D and 3D simulations of post couplers in order to develop an equivalent circuit model which can explain the post coupler stabilization working principle and define a tuning strategy for DTL cavities. Simulations and equivalent circuit results have been verified by measurements on the Linac4 DTL prototypes at CERN.
