【 摘 要 】

The SDHCAL prototype was completed in 2012, and exposed to beams of pions, electrons of different energies at the SPS of CERN for a total time period of 5 weeks. The data are being analyzed within the CALICE Collaboration. Preliminary results indicate that a highly granular hadronic calorimeter conceived for PFA application is also a powerful tool to measure hadronic particle energy. In addition it was found to discriminate efficiently pions from electrons. The use of multi-threshold readout mode shows a clear improvement of the resolution at energies exceeding 30 GeV with respect to the binary readout mode. New ideas to improve on the energy resolution using the topology of hadronic showers such as the Hough Transform technique are studied.
