Description
In 2006, the silicon tungsten calorimeter prototype developed by the
CALICE Collaboration was irradiated by low energy electrons (< 6 GeV) at
DESY and electrons and hadrons (pions and protons) of energies from 6 GeV
to 50 GeV and 80 GeV, respectively, at CERN. Obtained data demonstrate
superb shower patterns, determined mainly by a small Moliere radius of
tungsten and fine granularity of silicon sensors. Such a calorimeter functions
to a great extent as a tracker and meets requirements of particle flow
concept for the analysis of e+e- collisions at future linear collider. The
concept of the silicon-tungsten electromagnetic calorimeter, analysis of test
beam results and characterisation of the calorimeter prototype which
operated most of time in combination with the TileCal hadron calorimeter
and tail catcher prototypes will be presented together with the outlook and
future R&D plans towards the final calorimeter design.
