Difference: FJPPLHighEnergyPhysics (12 vs. 13)

Summary :
A compact and highly granular electromagnetic calorimeter at ILC is one of the key requirements for PFA high precision jet reconstruction and realization of ILC physics potential. R&D of silicon-tungsten calorimeter is the goal of this project. We plan to finalize the optimization of the ECAL geometry (dimensions and number of layers), to build and to test a detector (so-called "active sensor unit", or ASU) with 1024 channels per PCB serving 4 silicon sensors with 16x16 pixels, improve the DAQ software and to work on integration of several ASUs into one ILC full-scale detector. In parallel, we plan to test various designs of silicon sensors and their radiation hardness.
