Mechanical structure/tungsten/FEBs:

Beam-tests - will use the old tungsten structure in the November 2021 tests;

Yan with the help of Anton will produce an official table of the sensors and sensor layer sizes and also the number of sensors per layer; 

Jakub and Marek are considering to fit all FEBs of one layer into one board to facilitate connectivity and reliability; advantages and disadvantages are still being considered; top closure of the ECAL will have to wait till this is understood.

ECAL shielding:

Sasha replaced 5mm Pb beam-shielding by 15mm of tungsten; Shan showed that the background of Al window + W is half of that of Kapton window +Pb;

Sasha will have a look at the flux of particles that may hit the FEB boards; a height of 10cm above the silicon layer will be assumed to estimate whether "single-event-upset" may be an issue.
