A Scintillator Tile Hadron Calorimeter for the e+ e- Linear Collider Detector
-----------------------------------------------------------------------------
An overview is given on the concept and design of a LC hadron
calorimeter in the frame of the CALICE collaboration and general studies
for a scintillator based option with high cell granularity and analogue
signal readout are presented.

The concept is tested in detailed measurements with a 15 x 15 x 70 cm**3
scintillator/iron sandwich prototype with 0.5x5x5 cm**3 scintillator
tiles exposed to the DESY electron test beam. The tiles are readout by
photodetectors via inserted wavelength-shifting fibers. As
photodetectors 3 different candidate types were used in separate
calorimeter test series: Multianode Photomultipliers (MAPMs), Avalanche 
Photodiodes (APDs) and Silicon Photomultiplieres (SiPMs).

The performance of the SiPM and APD equipped prototype is compared with
the results from the Photomultiplier readout. Detector resolution,
linearity, calibration and stability are discussed, and the energy
response is compared with detailed simulations.
Based on this experience, a 1 m**3 prototype sandwich calorimeter will
be built to collect data in hadron and electron test beams at various
particle energies. Large quantities of such data are needed to study and
optimize the reconstruction of energies and angles of individual
particles in narrow jets. The expected performance is demonstrated with
some promising results from simulation studies.
