Abstract

The SDHCAL technological prototype is a $1 \times 1 \times 1.3$~m$^3$ high-granularity Semi-Digital Hadronic CALorimeter using Glass Resistive Plate Chambers as sensitive medium. It is one of the two HCAL options considered by the ILD Collaboration to be proposed for the detector of the future International Linear Collider project. The prototype is made of up to 50 GRPC detectors of 1~m$^2$ size and 3~mm thickness each with an embedded semi-digital electronics readout that is autotriggering and power-pulsed. The GRPC readout is finely segmented into pads of 1~cm$^2$. This proceeding describes the prototype, its operation and its performance in energy reconstruction. Aspects of the GRPC readout modelling and comparisons with simulations are also presented.
