A Scintillator based calorimetric system for ILC
The CALICE collaboration has collected test beam data with several calorimeter
prototypes for ILC. In particular a system with ECAL and HCAL both scintillator
based was in the FNAL test beam in year 2009. The highly granular calorimeters
adopt the state of the art technology in scintillator readout via silicon-based
photo-detectors (SiPM). As the first calibrations are becoming available for the
more than 10'000 channels, it is time to start hadronic shower analysis
exploiting the combined system if ECAL and HCAL. Energy density weighting
schemes and particle flow algorithms will be tested on a fully scintillator based
system and compared to a previously analyzed system including a Silicon-Tungsten
ECAL.

Particle Flow on a tungsten calorimeter system
The CALICE collaboration has collected test beam data with several calorimeter
prototypes for ILC and CLIC. In particular,the absorber material of the HCAL has
recently been changed from steel to tungsten.
A system with ECAL and HCAL both utilizing tungsten as absorber will be in the
CERN test beam during year 2010/11.
The highly granular calorimeters adopt the state of the art technology in scintillator
readout via silicon-based photo-detectors (SiPM).
Test of the Pandora Particle Flow algorithm for shower separation
can be performed on real data, and will validate the detector optimization
studies for the next generation experiments at ILC and CLIC.
