The Paschen curves give the breakdown voltage between two electrodes as a function of the distance between them. In this communication we present the Paschen curves for different pure gases and gas mixtures, when the electrodes are those of the ATLAS NSW micromegas detectors, $i.e.$, the resistive strips and a stainless-steel mesh.
