1. A resistive plate electrode gas detector comprising a first resistive plate electrode and a second resistive plate electrode that are configured to be biased through an high voltage power supply and each one is configured to be connected to a front-end electronics, wherein the first and the second resistive plate electrode are coupled parallel each other so that the resistive surfaces of each of them are faced each other defining a gas gap configured to contain gas, wherein the first and the second resistive plate electrode are each one a resistive plate electrode comprising a supporting plate coupled to a layer of polymer material on which a DLC layer is deposited that is connected to a connection assembly configured to be connected to a high voltage power supply, wherein the resistive plate electrode has a surface resistivity that is modulable on varying values of one or more deposition parameters of the DLC layer.
