 | Design of the ECal end-cap. |
 | Exploded view of half a long slab. |
 | 15 mm thick carbon HR plate with inserts and aluminum rails. |
 | One layer molded (3 alveoli, L~=~2.490 m, wall thickness 0.5 mm). |
 | Shearing test: progressive loss of stiffness for the dummy structure. |
 | Composite simulation: optimisation of rail localisation and module displacements. |
 | Fastening system on HCAL. |
 | Left: EUDET module equipped for thermal tests with 15 dummy slabs directly connected to the heat exchanger. Right: Thermal analysis of module: the passive cooling is satisfactory with maximum variation of temperature of 2.2$^{\circ}$C for the barrel modules and 6$^{\circ}$C for the longest end-cap modules. |
 | Left: Design of connection of heat exchangers with one copper drain extremity. Middle: heat exchanger for 15$\times$2 connections. Right: location of cooling system on one Si/W ECal barrel module. |
 | Thermal test results |
 | Left: cooling station in constuction. Right: global cooling system. |
 | Cooling test area with a drop of 13~m at LPSC. |
 | Heavy tool for module integration. |
 | Transfer of ECAL quadrant on quadrant insertion tool (ALICE like). |
