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, Tokyo University plans irradiation tests and Kyushu University - tests of different designs of silicon sensors.

Summary :
R&D of distributed computing for future large projects like ILC
•Evaluate and gain experience of emerging technologies such as cloud
•More studies on data storage and data transfer
•Both topics will be seen from the long distance point of view

To exchange ideas and knowledge between the two centers
•Re-establish the collaboration beyond the previous Comp_3 project
•Long-term collaboration has a benefit
