This technology is an interface between a detector vessel and a readout structure for an avalanche particle detector, in particular for a MicroPattern Gas Detector (MPGD) such as the MicroMegas detector.
In this invention the various elements of the structure are optimised in such a way the electronic signal is not lost through the resistive layer but is propagated to a separate plane, carrying read-out pads or strips, by capacitive coupling. There is complete separation between the Micromegas detector and the readout electronic plane.
• Reduces the charge released by Micromegas during spark formation. It provides spark protection to electronic.
• Easily accommodates any readout electronics by separating detector function and electronics function
• In the case of using integrated pixel chips this structure would solve a technical problem, related to the implementation of many chips, without creating dead space.
