[Solid_ec] EIC R&D proposal on EMCal

[Jin Huang]

Hi, Xiaochao, 

One quick comment on Fig 1: 

Comparing to the shown square matrix, a triangular matrix of WLS hole patter should be more efficient, both for light collection and for matching the hexagon module shape (comparing square shaped COMPASS module). For a triangular matrix, we could keep the area per fiber to be 1cm^2 (initially) or even larger (later, to keep average distance of hit position-WLS to be the same).

Cheers

Jin
