Detector-readout interface for an avalanche particle detector

A detector-readout interface for an avalanche particle detector, comprising:

• a gas chamber of said avalanche particle detector, said gas chamber comprising an amplification gap or a collection gap;
• a resistive layer formed at a bottom side of said gas chamber;
• and
• a dielectric layer formed under said resistive layer;
• wherein said detector-readout interface is adapted to be capacitively coupled to a readout board that comprises readout electronics for said avalanche particle detector;
• and wherein the thickness t2 of said dielectric layer and the thickness t1 of said amplification gap or collection gap, respectively, are chosen such that t2<t1×∈2/∈1, wherein ∈1 denotes the dielectric constant of a gas filling of said amplification gap or collection gap, respectively, and ∈2 denotes the dielectric constant of said dielectric layer.
