Description

The traditional purpose of the ECAL of the ILD experiment is to measure neutrals
(especially photons but also the interacting neutral hadrons) while tracking the
charged particles for particle flow algorithms.
A highly granular Silicon-Tungsten ECAL (SiW-ECAL) is particularly suited for these tasks.
The SiW-ECAL faces many technical challenges: the main ones have been solved,
some remains to be tackled, while new ones, such as a precise timing, still need to be fully evaluated.
It is proposed here to make a review of the art on all these issues.
