Dead time spectra for Am241 Source and 2mm pitch double gap chamber (M2R2). The Spectra where obtained by averaging the discriminator output and differentiating this curve. A 220pF Capacitor was added to the 50pF from the wire pad. This simulates a very large (R4) wire pad. The double peak structure has is due photons ionizing the gas between two wire pads .... at least that's the idea for the moment.
