Abstract: The basic prototype of a tile hadron calorimeter (HCAL) for the International Linear Collider (ILC) detector has been realized and extensively tested. A major aspect of the proposed concept is the improvement of the jet energy resolution by measuring details of the shower development and combining them with the data of the tracking system (particle flow). The prototype utilizes scintillating tiles that are read out by novel Silicon Photomultipliers (SiPMs) and takes into account all design aspects that are demanded by the intended operation at the ILC. Currently, a new 12 layer prototype with about 2500 detector channels is under development. The new prototype will be used for the first time in the proposed configuration for the measurement of shower profiles and shower development in time using the hadronic beam at the CERN PS test facility in fall 2014. Alternative architectures for the scintillating tiles with and without wavelength-shifting fibres and tiles with individual wrapping with reflector foil will be tested as well as different types of SiPMs. Additionally, detector modules for the CALICE scintillator-based electromagnetic calorimeter, that follow the proposed HCAL electronics architecture, will be part of this new prototype. A new data acquisition (DAQ) is currently under development for the detector configuration and operation. Despite the on-detector zero-suppression, the remaining huge amount of data demands a high efficiency for the new DAQ’s processing and online-monitoring capabilities. Results for the commissioning of the new prototype will be shown including results from a first test of a steel stack with 8 detector layers in the DESY electron test beam facility.
