lead foil + glue + fiber layer
repeat 10-15layers
wait for glue curing with 1.1 atm pressure (pistons)
90 degrees bending (in case of end-cap modules)
repeat up to ~ 200 layers(one module complete)
General Structure: All modules fibers almost to the incoming particle
(1) Barrel:
24 modules:
Trapezoidal section(52-59) X 23 cm2
cylinder diameter = 4 m length = 4.3 m
(2) Endcaps:
32 modules each:
Rectangular sections(9-27) x 23 cm2
0.7-3.9 m length (bent on both sides)
2 circles of 4 m diameter
