Assembly of a supercrystal (SC) of the CMS endcap electromagnetic calorimeter

The first three pictures show the insertion of the first three rows of crystals into the supercrystal SC03 on Jan. 2004 and the completion of the SC endstops. Fig. 4 shows a complete supercrystal and Fig. 5 its components (alveolar, interface plate, housing, optical fibre, insert, crystal and VPT, endstop). A set of 25 inserts is shown in Fig. 6, while Fig. 7 shows housing, interface plates and inserts. Finally, a SC rear view showing the Vacum Phototriode (VPT) wires through the inserts can be seen in Fig. 8. Fig. 9 and 10 show two supercrystals under test on Dee F and R, respectively.
