Descripción
The Semi-Digital Hadronic Calorimeter (SDHCAL) is a highly segmented sampling calorimeter developed by the CALICE collaboration having in mind the future ILC experiments. The SDHCAL uses Glass Resistive Plate Chambers as active medium and the readout is done by 1x1cm2 pads using 3 different thresholds. A 1m3 prototype was built and successful tested in beam tests along years for which the CIEMAT group played a major role. The new generation of this type of calorimeter should include precise timing information (T-SDHCAL), better than 150 ps which can be obtained with multigap chambers (MRPC) instead of the single gap used till now. This development should be accompanied by new readout electronics with resolutions of tens of picoseconds. Operation in a circular e+e- is more demanding on power-consumption with respect to ILC because the electronics cannot be power-pulsing and, in addition, active cooling could be needed to sustain the higher rates. The T-SDHCAL R&D is included on different working package activities of the DRD6 and DRD1 collaborations, and, in Spain, two groups, CIEMAT and University of Cordoba, are involved. The work will also include software developments for shower reconstruction and particle identification aiming to implement IA techniques. Synergies with other DRD6 and DRD1 groups developing micro pattern gaseous detectors (MPGD) have also been identified.
