Dear all,
please take a look at the draft version of two abstracts, which we plan to submit to ICHEP from CALICE.
They are complied by Frank and me from your proposals. The size can be about half a page.
Your comments/corrections/additions are very welcome.
Thank you in advance.

Technology Development for Highly Granular Calorimeters
The CALICE collaboration is developing highly granular calorimeters primarily to establish those technologies for experiments at a future lepton collider optimized for particle flow event reconstruction. These technologies are now also finding applications in other areas, such as upgrades for the LHC. After the successful validation of the principle of imaging calorimeters with different electromagnetic and hadronic physics prototypes, the emphasis has now shifted to technological prototypes that address system issues relevant for full detector systems and production techniques amenable to mass production. At the example of the SiPM-based Analog Hadron Calorimeter and the RPC-based Semi-Digital Hadron Calorimeter, we will discuss new developments on electronic integration, the fabrication of large size detector elements extending over several square meters and techniques for the mass production and assembly of scintillator tiles. We will also report results from recent beam tests of such elements, and give an outlook on the development towards combined beam tests of different CALICE technological prototypes integrated via a common DAQ system.

Test Beam Performance and Detailed Studies of the Structure of Hadronic Showers with Highly Granular Calorimeters
The highly granular calorimeters developed and tested by the CALICE collaboration have provided large data samples with precise three-dimensional information on hadronic showers with steel and tungsten absorbers and silicon, scintillator and gas detector readout. We will discuss the performance of the RPC-based Semi-Digital Hadron Calorimeter in terms of energy resolution and pattern recognition, compared to Geant4 based simulations including a detailed modeling of the RPC response. The influence of granularity on the resolution obtained with digital, semi-digital and analog reconstruction method will be demonstrated based on the analogue HCAL data and simulations. We will also present the results of the performance studies of the combined scintillator-based calorimeter system (Sc-W ECAL, Sc-Fe AHCAL and Sc-Fe TCMT). The validation of the system with muons and electrons will be discussed as well as the single hadron energy resolution using both classical energy reconstruction and software compensation techniques in comparison with the predictions of Geant4 simulations. We will show the parametrisation of the radial development of hadronic showers in the Sc-Fe AHCAL and the progress in the predictions of several Geant4 physics lists. The results of the detailed measurement of hadronic showers in the SiW ECAL in terms of integral observables will be also presented; the observables, which characterise the interaction region and tracks produced by secondaries will be analyzed and compared to Geant4 simulations.
