Beam studies of thin single- and double-stage THGEM-based detectors are presented. Several 10 x 10 cm2 configurations with a total thickness of 5-6 mm (excluding readout electronics), with 1 x 1 cm2 pads inductively coupled through a resistive layer to APV-SRS readout electronics, were investigated with muons and pions. Detection efficiencies in the 98% range were recorded with an average pad-multiplicity of ~1.1. The resistive anode resulted in efficient discharge damping, with few-volt potential drops; discharge probabilities were ~10-7 for muons and 10-6 for pions in the double-stage configuration, at rates of a few kHz/cm2. These results, together with the robustness of THGEM electrodes against spark damage and their suitability for economic production over large areas make THGEM-based detectors highly competitive compared to the other technologies considered for the SiD-DHCAL.
