Hello everybody,

It is not exactly correct 80x360, because we will use 
4.2 cm x 4.3 cm blocks for first 1000 and 4 cm x 4 cm for
next 700 and hopefully at least 300 3.7 cm x 3.8 cm
So, the area is larger and arranged in C-shaped.
The actual shape of the CDET can follow C-shape.
However, the vertical size is limited by 300 cm as it was
in GEM-based plan. Larger vertical size require extra
funding.

Mahbub, I can't attend the meeting attend today, but need to caution you 
that the size of the coordinate detector needed for GEp(5), although not 
frozen at this point, is likely to be about 80x360 cm^2, if we just use 
the lead glass from BigCal, or larger if we find more bars /PM/bases.
Regards. Charles
